Alero Install

[Ryan from Ohio]

So it begins...

Heres what I got:
Alpine CDE-7830 Old School CD only player
Eclipse EA4000 Amplifier
5.25" Rainbow Profi CS 230's
1 8" Tang Band 8" NEO woofer

And here they are:

Oh and my bright RED Alero:

[Ryan from Ohio]

Game plan is stealth yet beauty.

Looking to corner load the car, drivers corner. I am going to glass the sub in. Have a small plexi window on the bottom and an acrylic mirror to see the rear of the sub.

Or just glass it in same corner, no stealth.

Not sure yet.

Problem with doinbg this stelth is to get grille cloth that matches the carpet in the rear- which probably cant happen...

So Im about to eat and get to work!

Ok the subs is going to down fire. The port will come out the side. This will be stealth except the single port...

[brisgreat1]

sounds cool
make sure u post progress pics and finsihed product
r u mounting comps in stocks or you gonna fabricate something?

[Ryan from Ohio]

Will be mounting them in modified stock locations, I believe.

The doors house 4x6's currently and I know I will need to modify. Im about positive I will have to modify the tweeters in the sail panels.

I will probably go ahead and cut up the plastic and purchase replacements from the junkyard just in case.

[Ryan from Ohio]

Ok got the radio today and all the stuff to install it.

I pulled it out of the box to give it a quick bench test with the power supply.

First thing I notice the buttons on the left dont light up as they should.

Try to put a CD in and it wasnt having it... Wouldnt eject anything either...

Moving onto the tuner. Ok no sound coming out of my speaker...

So lets see, Im just a tad bit unhappy right now. $55 and no workie... Advertised as working, non DOA yadda yadda...

Im just going to go buy a new one! F this shiznit!

[smoker]

if your are real pissed you should just give me that alpine, thatd show em......

[solacedagony]

I would like to know how that TangBand sub puts out. Let me know what enclosure/volume you put it in and whatnot. I wanted to try putting a cheap little speaker like that in a transmission line or something crazy and see what I could get out of it. Thanks!

[Ryan from Ohio]

12MM one way xamx...

Its gonna pound real nice for an 8" sub!

[a32nissan]

i though that rainbow was only distributed by 2 dealers in the U.S.

one in jersey and the other in Atlanta. are there more now?

[solacedagony]

Ryan: I saw Tang Band makes 6x9 subs also with like 10mm xmax. And for the price? God dang, worth a shot.

[Ryan from Ohio]

I got the amp in today!!!

I was so excited I heard the front door open and I kumped up and poped out it like a jack in the box! lol

I had to take the rear cover off and send a pic into amp guts! THere wasnt one there, but will be now!

THis amp is ver refined looking! Nice carbon fiber accent, very classy!!!

Came in and she was as new as new can get! THe protective wrap was still taped on!

[solacedagony]

That it a super pretty amp.

[Ryan from Ohio]

Ok I spent some time with the head unit today.

The seller has said he will refund my money and to just keep the deck as its not really worth sending out for repair.

At this point I figure I dont have much to loose... So I tear into it!

Ive found that one little spring was missing after removing the front cover. I removed the CD mechanism to look for the spring, nadda. Couldnt find it anywhere. So I start to look in the packagin.box he sent it in. AMongst the peanuts was a small spring!!!

So I put the spring on where it goes, put it back together far enough to test.

Plays CDs now! There is AC voltage at the RCAs, no output thru the internal amplifier however.

One thing I will not, that there were two sets of wires soldered on. And they simply cut thruough the wires... Wonder if it grounded them out and fried something...


Dunno...

:bow

[cargodz]

Any luck now that you've had a few more days to play around with it?

[Ryan from Ohio]

I gave up on the internal amplifier...

Im going to eventually get another radio to put in the Alero, dont know when. Until then, it will do.

But to say the least havent been messing with the install. I took on another contract and its got me way tied up. Actually I shouldnt even be here right now...

[brisgreat1]

damn, i really wanna see ur fabd tweets

[Ryan from Ohio]

Ok, slight change of plans.

I was looking more into the trunk, and to be honest theres really no good way to stealth it.

Im going to just go ahead and build up a 6th order bandpass for the single 8" sub.

I got some fiberglass cloth today, 24" x 36". SO whatever I bo a combo of the box and or amp rack will have a top layer og Carbon Fiber to set off the amp ;)

Now I just gotta figure out what resin I need to use to make it all ncie/shiny/CLEAR.

[Ryan from Ohio]

And I just got outbid on another denon made Rockford HU on e bay...

Shit, I put $415 on it to. I cant believe I got outbid, thats a ton of $$$ for it... lol.

I figured it wouldnt break $350 area...

Seen one on their buy it now for $900...

lol, right... :rolleyes

[Ryan from Ohio]

As most know I picked up a McIntosh HU.

Today I designed my 6th Order Bandpass.

Here are the pics of it. Intent is to test the box FIRST, then if its good get a plexi window cut with my LOGO in it ;)

Heres the pics:

http://caraudiocentral.net/ryan/images/iso1.jpg
http://caraudiocentral.net/ryan/images/iso2.jpg

Yes, Bill isnt the only one with CAD skillz ;)

Anyhow, 2" ports, three on the rear chamber. They are spaced to come up to where the rear 6x9s were in the alero. So its ported pretty much into the cabin ;)

Will be building three boxes tomorrow, weather permitting and Im feeling decent...

[smoker]

i like it i did someth9ing like that years ago with a solobaric 8 and a ppi sedona amp and it souded great

[Ryan from Ohio]

The graph is very promising.

The problem with this sub is they tout it as a perfect small box sub. WHen modled it doesnt have a very good curve in sealed. In ported tuned low with a SMALL box (28 Hz, .25 cubes) it looks like most subs sealed...

Trying to get gain results in a nice spike follwed by a DIP bellow 0 dB...

ill trade you my clarion for it, straight up you dont even have to pay extra, in fact ill pick up the shipping bill

[Darthness]

nice

[CaptainPioneer]

I hate you :( thats not fair! I want it!!!!!!

[solacedagony]

She's a beaut. I like that old style dual turn knob look. Don't like the fact that I would have to mount another processor somewhere though :)

[cargodz]

Truly a thing of beauty:thumbsup

[CaptainPioneer]

ehh ill think ill pass on that... allthough i wish i could just buy it right now :(

[Ryan from Ohio]

Joe, or anyone...

Know about these optical cables the are used on the HU to the DAC?

I got a cable, I see where it plugs into the dac (obvious) but I dont find it fitting any of the others on the HU...

grrr

[Ryan from Ohio]

OK nvm I found it...

There just some other cables on it Im unsure what they are for...

Also, is the optical out for both channels or just ONE???

I take it I will need at least 1 set of RCAs from the HU directly to an amp/eq. THen a set from the DAC to the amp (like a 3 foot set or less)?

[Ryan from Ohio]

http://www.caraudiocentral.net/ryan/images/alero/8-6th1.jpg

I caulked it up and put the top plate on it.

Need to cut the 5 ports tomorrow @<hidden> work. Try to keep it accurate!

:thumbsup

[Ryan from Ohio]

http://caraudiocentral.net/ryan/images/alero/8-6th2.jpg

OK, not NEAR as loud as that 12" box I did. Really not loud at all :(

I guess it IS a single 8" sub.

Ive never built/seen/used a box like this before, 6th order bandpass.

Its buite strange. The lower FSs the air really comes out the front side (small chamber). The higher FS the air is on the rear chamber... Strange.

Anyways Im going to also build a single ported box for the sister to the one in this box. WHen I install I will try both boxes and run with whats best. Maybe add the other sub and simply buy another amp for my highs (EA2000).

[Ryan from Ohio]

Rear end has been gutted and power wire thru firewall.

Time: 45 minutes. That includes carrying all the pieces up a flight of stairs ;)

This car has no screws! Its all snap in connectors...

Pics to come.

[cargodz]

Looks like you made some progress of your own today:)

P.S. Thanks for all the help this weekend... I'll have my own pics up in a bit ;)

[Ryan from Ohio]

Fit kit installed.

DC-DC convertor installed.

Pass door panel and comps removed. I will need to refab the sail panels- hack the shit outta them. The 5.25" speaker thats replacing the 4x6 will need an entire housing fabed up. I will need to get some assistance angling the speakers/tweets. Got a game plan though.

All in all the about 3 1/2 hours I got into this, much is done.

Tomorrow weather permitting I intend on getting the box in and amp rack designed.

[slick94prix]

What do you plan on doing for the mounts?

[Ryan from Ohio]

glass for sure.

I will have to add 4 holes into the doors, attach via sheet metal screws and PL glue. Seems to be the glue of destiny!

Should be a relatively easy project. Make two sets of baffles. Mount the bottom baffle. Get help aiming the baffle, then hot glue it together. Fleece then glass it. Done.

[slick94prix]

Sounds like a fun little project.

[Ryan from Ohio]

Shouldnt be to bad.

The hard part is the aiming of the mids. Thats what will make or break it.

[slick94prix]

Definately!

BTW, I need to get hold of you sometime on aiming speakers anyways. Just hit me up on AIM when you get on next.

[geolemon]

Very cool looking amp... cool looking head unit, but I still maintain that the radio isn't going to work on that guy - you'll have to let us know on that! :D

I've played with the 6.5" version of those subs actually - pretty remarkable guys. That thing SHOULD get pretty damn loud - you know, for an eight anyway. If you've got it tuned to pretty much stay above 40hz (probably have to, like most eights) - maybe 40hz to 80hz - you should be able to dial in a pretty good amount of dB out of that and still stay pretty flat.

If you can't, I'm currently running a dual-eight setup that is a dual-chamber tri-vented enclosure, that bears some resemblence to a bandpass box in that it has two differing volume chambers and two discrete tuning frequencies.

What I like about a DCTV box that is a benefit over a bandpass box, is that with a bandpass box you yield the displacement that comes from the combination of the two ports (or one port, for a 4th order BP ;)). With a DCTV box, you yield the displacement of the sub, AND the two ports. :cool:
And - with a DCTV box you inherently get a frequency response that compliments the cabin gain of your interior.

I'll put it to you this way - my dual-8 DCTV box is able to reach at least 130dB, likely more - it's loud enough that it can cause ear pain on heavy bass music, certain rap songs... I'll have to break out the meter one of these days.

Just a thought - if that bandpass box isn't quite cutting it, I'm sure I could give you a design for a DCTV box to fit that exact same space - with that box your sub would also be firing out the top, if that would work. Just a thought, might be fun to play, if that box isn't going to be locked in there too permanently. ;)

[Ryan from Ohio]

The box will slide up to the front of the foldown seats with the ports firing through the 6x9 areas into the cabin.

Ya at 40-70ish Hz this thing is pushing some air.

I may have to add a third port on the front.

Ya I will have a look at that design. I have TWO of these subs. Ones already in that box (can come out). I got power for two if I find another amp for my comps (EA2000).

Now why wouldnt this Head Unit work, or are you just saying that? Kinda a bit nervous as this is the second time someones said something along them lines. I paid a pretty penny for it :( It better work with my system!

[geolemon]

It's not that the head unit won't work - but the radio part of it.

Radio frequencies in the United States are broadcast on a different format and different set of frequencies than they are in Japan.

Wasn't this the HU you bought, that was an OEM piece in a car only sold in Japan? If so, it's got a Japanese radio tuner in it, not a USA AM/FM tuner.

But hey, who knows what you'll pick up on THOSE frequencies, if so! Maybe our government uses those frequencies for confidential communication channels. :p
You don't have any FM modulated goodies, like an XM tuner or iPod, right? If so, probably no big deal.

[OnYrMrk]

Chris, that head unit is an American Unit, that preceded the MX406. The headunit that you are thinking of is the Double din model made for the Subaru Outback and the clone sedan.

[Ryan from Ohio]

I never bought that HU. The seller kept giving me the run around about info on it. Kept claiming stuff and couldnt verify it. He actually attacked me.

Oh ya, he wouldnt provide a pic of the rear of it. CLaims it has RCAs out.

I found one on E bay awhile back for $200 w/amp. The thing didnt have RCAs on the back. I think that douche bag is trying to rip someone off...

[geolemon]

Oh, I see.
I thought you bought that Japanese OEM one - you had linked me to that Ebay auction before.

Where did you find that one? I always thought those HU's had a cool look to them. :cool:

[geolemon]

:dancing :surprised

Oh - that must be that model that has the robotic arm that comes out from behind the faceplate and gives you a tug-job as you drive down the street.

Those features don't come cheap. :p

[Chris from Washington]

Oh - that must be that model that has the robotic arm that comes out from behind the faceplate and gives you a tug-job as you drive down the street.

Those features don't come cheap. :p


LOL!!!!

[MobileAudio219]

Oh - that must be that model that has the robotic arm that comes out from behind the faceplate and gives you a tug-job as you drive down the street.
Those features don't come cheap. :p

yeah, thats the one. this happens to be one of the ultra rare models, it has the "celebrity" feature, which lets you pick the hand of any celebrity. ryan has his set to lindsy loanhand... hahahahahahah

[Darthness]

so ryan, what ever happened to the spl car you were going to build? is that on hold/

[Ryan from Ohio]

definetley on hold.

Actually it may get sold, need $$$.

[Ryan from Ohio]

RCAs arrived today.

When stinger gives you a length on RCAs its rca tip to tip! I figured it was the length of the wire before they y off...

Still will work though.

Searching for a way to run the RCAs/Opticals thru this car...

This I found a place. Entire passenger side is ripped out, glove box and all... lol

This car isnt to fun to play with under the dash! Especially trying to go from the radio to passenger side :(

BTW the Stinger Exper series are pretty nice looking RCAs. THe cable is a bit bland being just rubber. THe y off is sexi black chrome. Same with the end. BTW they are twist lock. SO you plug them in, give em a twist and they wont slip off!!!

[smoker]

yea you dont want to try to pull them straight off either.....i had a customer pull the rca input off a dx1500.1 like that once......

[Ryan from Ohio]

I always twist and pull RCAs.

[cargodz]

This car isnt to fun to play with under the dash! Especially trying to go from the radio to passenger side :(

Most GM's are always fun to work on:unwell028
Thanks to all the engineers at GM that have too much time on their hands and overkill everything:p

[Ryan from Ohio]

Well I come to a snag.

THe METRA fit kit I got wont allow the radio to push back far enough to clear the metal support in the back.

Thats after trimming off the plastic one...

So in a few Im off to another store to try my luck with an American International kit...

If that doesnt work either, Im going to be very uhappy...

[Bwcad1]

cut it out thats what i did on my blazer

[Ryan from Ohio]

http://www.caraudiocentral.net/ryan/images/darnedbar.jpg

:surprised

I might be able to get back and get the sheet metal part. Im not going to even TRY cutting that bar however...

Its where some of the plugs come out the rear end on that HU...

[Ryan from Ohio]

Radio is in after a very tought day of wrestling with it...

Wires are run all the way around.

All thats left tomorrow is installing the comp set, finding a ground, building an amp rack, mounting and hooking that shiznit up!

[geolemon]

Did you have to cut?

Anything that's not a removable panel I would have to think twice, three times, four times... a beer on the couch... wait a week... think about it again, six times... ask mentors how they would handle it... and even still probably couldn't bring myself to cut it without a solid plan established for restoration. :p

I groan when I even hear about people who cut factory wiring harnesses (who hasn't heard of a wiring harness adapter these days? :rolleyes:), so cutting a dash support would certainly get my warning light blinking. :help:

[Ryan from Ohio]

Oh ya, cut I did!

Thats about what I did Chris. I played around a bit, tried thinking out a few scenarios. Just kept coming up empty handed.

THe plastic I trimmed away really had no real use. THe stock unit has that tang that went into it- thats it.

The metal piece I cut had no real relivence either.

All it did was giving it someplace to screw down to on the hind end of it.

http://caraudiocentral.net/ryan/images/alero/darnedbar2.jpg

There areas on the inside of the lines is kinda where I trimmed. Just up to the opening. I also cut the flat piece of metal in the back. Again, it just providied a place for the plastic to bolt to in the rear.

Talking with the people @<hidden> aleromod.com it tends to be a somewhat common event...

[geolemon]

Yep, that doesn't look like a piece of structural metal. GM head units have always had that little nipple sticking out of the back of them - I see that they still do. :p

When I installed my CD changer in my rear passenger armrest, I had to trim a little bit of metal also, down to about half the width that the strip of metal bracing used to be... I ended up reenforcing it by welding a piece of small angle iron behind it.

It's not so much that "cutting is a sin", but cutting without thinking is. :cool:

I might still maintain that cutting factory wiring is a sin. ;)

[Bwcad1]

whos cutting the factory wiring? i must be missing something lol

[smoker]

a buddy of mine doing a system in his new 07 nissan somethingorother wants to do a pair of midbass in each door and he is afraid to start it for fear of screwing it up, so i told him about the "smoker method" of customization...........here it is in a nutshell..........just do it because if you screw it up you have no fear anymore..

[geolemon]

whos cutting the factory wiring? i must be missing something lol
I made the blanket statement about "cutting" [anything].

I just wanted to differentiate - cutting door panels I don't consider a sin (one would assume the cutting was the outcome of a plan ;)), cutting metal isn't something to be done without extensive planning, and cutting wire is something that nearly any plan would inherently lead you away from doing - and therefore I would generally (never say never) consider it a sin. ;)

There's a big difference between cutting metal vs. cutting wiring - even though cutting anything should never be done with a plan (there is that common tie :p), I just didn't mean to make a blanket statement about "cutting".

[Bwcad1]

ahh ok i was confused.

[Team AI]

I like peanut butter

[solacedagony]

I like peanut butter

Creamy, not crunchy :)

[captaincheesey]

Creamy, not crunchy :)


Nope, crunchy all the way. With strawberry jelly and sliced strawberrys. Preferably when they are in season though.

[Ryan from Ohio]

Dammit people...

FOr an 8" sub, it provides enough fill. Enough bass to get a little over the fronts, but not terrible.

The SQ is simply unbelieveable. Im sure it will only improve with some imaging with the tweets. Right now they are just kinda in there. Once aimed, will glue and finish them off.

Just need to iron out this DAC deal..

[geolemon]

I've got two eights in a DCTV enclosure that wraps around my spare tire that I relocated to my hatch floor - and it's got as much bass as a single vented 12". :cool:

And it's got a smoother frequency response [in-car] than a vented box.

[Ryan from Ohio]

Heres the latest purchase:

Pretty nice for $75!

Looks like it will do what I want. I was kinda holding out for a 1/3 octave, but this jumped out at the right time and has a nice look to it. Ive seen this same unit selling for $350 new, so it cant be to bad of a unit! lol, and a good deal!

The 6th order is currently out of the car. Its getting carpeted. Also Im going to be building a new box for its sister sub. SO I can switch it up a bit if I need more trunk space. Might go with a small ported.

The 6th is a bit big, but I spread it out...

So new box, some carpeting, now I need an amp rack and the final on the RCA situation...

[cargodz]

That'll make a nice addition to the system... and no the PG stuff ain't bad... just a lot of it overpriced for what it is.

[Ryan from Ohio]

Wait until you see the new box ;)

Its an SPL box- for a single 8" sub!

:surprised

Lets just say, them little 8's BEG for a ported box and to be tuned on the high side... lol...

We will haveta meter both boxes next time Bills out...

[cargodz]

Definately! :)
An spl box for 8"s is almost a contradiction in terms, but... I was impressed with only one of them... so I'm really interested;)

[solacedagony]

Dammit people... FOr an 8" sub, it provides enough fill. Enough bass to get a little over the fronts, but not terrible.

Yea, my XXX is way more than I need to match up to my front stage. Even at higher levels. I have it attenuated by like 18-20dbs right now... :bow

[Bwcad1]

ive seen 2 eights do a 151.

[Ryan from Ohio]

Well thats cool.

Whats the best you seen a $50 8" speaker do? ;) I think you guys see what Im gettign at.

Anyhow, here it is. Sex on the table!

I just ordered my new RCAs tonight... Another $100 worth... Ouch. Anyhow, I have all the needed RCAs on the way.

Tomorrow Im going to try getting my amp board cut up. Probably cant install it due to the cold weather and snow. Yes I have to work outside...

:(

[thedukey42]

Did you use any software or calculate anything to make that 6th order or did you just kinda wing it? Just wondering?
What are the tunings of the chambers?

Just wondering because I'm installing a pair of cerwin vega 8" & wondering what type of box to build for them.

Way to fight threw the build btw!

[Ryan from Ohio]

I used winISD.

Theres info on the box around the forum somewhere. Do a search for sixth order bandpass- it should come up.

All depends on the subs really. These modeled well, really well...

They dont model so hot in sealed or ported though :(

[Ryan from Ohio]

Rainbow Profi comps. The good ones with the CAL25 tweeter ;) The mids you cant see, they are fitted in the door via custom made fiberglass pods. Yes I know they are rough. I need to finalize my imaging after and RTA session and fill it/paint them.

Fuses for the DAC and the EQ. I take no chances with this level of equipment!

RCAs are Stinger Expert series throughout. Big 3 wiring is in progress- need motor- ground.

And thats that!

[swimmerdude]

Mmmm.... that stuff is very sexy Ryan;)

[Ryan from Ohio]

Ya...

I lost my one cheap 12 today. It lived a loud life and died doing what it did best.

It died rather strange though... It must short when it extends or something. Reads good ohm @<hidden> rest but causes the amp to go into protect when it starts to move... Oh well, back in the box and to Wal Mart to get my $15 back :p

[neumann]

sexy tweets:thumbsup
o, and btw, did you clean out that walmart on the way home from mike's? Me and ellert saw you pulling in there.

[Ryan from Ohio]

Nope...

was actually taking a short cut to Best Buy to snag a DVD RW drive.

[swimmerdude]

i have a question ryan.... can your pictures get any bigger.


LOL

[subster87]

I have a friend tossing around the idea of a 6th order bandpass on a 8 inch w7 would you be willing to share some advice on it with me?

[Ryan from Ohio]

Good luck! Certain subs react well, others- not so well ;)

[ChevyMuscle]

damn i love that vinyl...but i just cant help recognize those blue black and red wires thier so damn familiar...where did you get those from?

[Ryan from Ohio]

Some strange guy iin a black car that carries around a few thousand feet of each color

:thumbsup

[ChevyMuscle]

:surprised where could i find this guy?

so how does it sound now with the eq

[Ryan from Ohio]

Honestly, at this point Im not liking it.

I spent a whole minute or two tuning it, I need to spend a bit more time.

The system lost all its "warmth".

[ChevyMuscle]

yea i know that feeling...maybe you have so much soaund quality that it sounds bad.

Looks familar. Let me know when you get it installed I can hear what could have been.

[JeremyC]

I have a friend tossing around the idea of a 6th order bandpass on a 8 inch w7 would you be willing to share some advice on it with me?

Not sure about the 8, but the 12 and 13W7s aren't the best design for a ported or bandpass box. IMO, I wouldn't try it, but I would have to check up on the specs before I give you a final answer.

[Bwcad1]

if it likes sealed then a fourth order would be right up the alley. on top of that unless your friend has extensive knowledge of physics and accoustics i strongly recommend against it. bandpasses are very temperamental and slight changes can cause catastrophic results. TRUST ME ON THIS ONE! 90 percent of all woofers i have blown up were bandpass designs!

[cargodz]

Well you don't have a lot of time to make up your mind before Milan... definately let us know how it went ;)

In addition: Man why does it have to be my dads b-day, really wanted to go to Milan... I love the 1/4 Mile :(

[Ryan from Ohio]

haha... and I ended up not having to work. Just glad I got the call before I drove all the way up there. Bad thing was it was at night...lol

[Ryan from Ohio]

Ok,

Installed the HD Radio. Installed a Metra Universal amplified antenna (yes it sucks so not using it!), bondo'ed the sail panels and painted.

I want to install the other amp and W6V2 tomorrow. Maybe later tonight, dunno

[Ryan from Ohio]

Some new changes will be happening in the Alero... stay tuned ;)

[cargodz]

Well if you're driving it over later today/ tomorrow, then I guess maybe I'll get a sneak peak ;)
