what do everyone think about the Resonant Engineering SX 12"
and what would be a good amp to push 2 of em? each are 1000rms each
what would be the minimum rms wattage needed to push these to get full exercution?
im looking for good sound quality but also good bump I wanna keep around $300-$350 for the 2 subs and around $200-$250 for the amp
ps does anyone know when the koda 12" are gonna be out? i was also lookin at them but their not out yet
flat out, $250 is not enough money for even one amp to power 1 sub.
also, do you have an alternator that can handle 140+ amps of current, plus your cars required amount of current? say 200A total?
the SX is a great sub, baiscally on par with the XXX, just less Xmax. 1000wrms is what it takes to reach full excursion, give or take 100 watts.
a suitable amp would be JBL or Kicker 1200.1....and those are about $350-$400 i think. but i'd personally spend a little more for that sub, and take tender care of it.
btw, each of those subs is like $285. so you're talking $570 for 2 subs, and $800 for 2 amps.
that sub is pretty hardcore, i'd think it'd be wise to start with one, and then see how much room you have to grow with, hearing-wise.

I bet I can do it with far less :D ... say... 400 watts. heh

You can get max output out of those subs with around 400-500 watts RMS. The way to do this is put them in a large, ported enclosure.
And ignore what Jszar said, you won't need to spend $800 on amplifiers. Just get a good amp that can put out between 1000-1200 watts RMS and you will be fine. But the thing he said about the electrical system is true, but you should be okay with a 140-150 amp alternator.
i'm not going to argue justin, but be a little more courteous with your comments in reference to others.

Justin is just blunt, jszar. I know he means well... uhh, most of the time ;)

i was thinking about that but was told if i got with 1 sub and a mono amp that its not gonna be good sounding bass cause its only gonna hit on like one side and not both say u got ur left and right speaker unhook the right u have the left playing and thats what it would sound like thats how someone explained it to me is this true or are they misleading me and trying to get me to spend way more than what i need to?
they are misleading you most definetly. that analogy they gave you is completely wrong.
if Justin or Will want to explain the way to make a box that'll allow you to reach full excursion with only 400 watts, then you can get a decent amp for what you're looking to spend. but note that you'll have a huge box for your sub, and i dont know what car you have....so make sure you plan/have the room for a big box before you buy anything. make sure you still have enough money for a good wiring kit, and building supplies for that box too.

i have a 92 honda accord lx 2 door 5 speed
thanks for the info cause that will save me alot of money just going with 1 sub and amp
dont think i mentioned but i want it to hit hard yet great sound quality
i was thinking a jbl 1200.1 and the re sx 12"
will that give me what im looking for?

you can get that jbl 1200 and get the 2 sx's, youd give em 600 each, you will be pulling a LOT of power(not counting yorue speaker amp) you might need a better alternator.
well, you can do with less power if you take justin and will's idea. that'll save you $50+. but you'll have no trunk left.
an SX is a great choice, and a jbl amp will do just fine. considering its all stock...you'll need a jbl 600.1, because a 1200.1 will draw to much current from the stock alternator.
dont order from RE this week though (oct 12th), i guess they're getting a bunch of orders lately and so their shipping is behind like two weeks. I ordered my sub around the 22nd of september and it isnt shipping out til oct 15th or something. Was supopsed to ship the week of the 5th :-/
anyways they(RE) have absolutely GREAT customer service so if you wanna call them they will help you step by step how to build a ported enclosure. I was talking to the guy and i said " yeah im not that good, i dont wanna mess up a ported box and have it sound terrible" and he told me that it isnt THAT hard to make a ported box and he could walk me through it if i wanted to. anyways he helped me get the right size for my sealed box and was very patient with me. now dont take that as building a box is really easy. sealed is pretty simple if you have some backround with power tools..never tried ported though. have patience though..
should be less than or equal to 3/4" MDF (like 20$ for a sheet at home depot...beware..its crazy heavy)
lots of wood screws, maybe some heavy duty screws
power drill to predrill holes/screw
liquid nails
caulk
jigsaw
tablesaw/skill saw
thats not everything but just trying to give you an idea of the supplies you need for a box..hope i helped somehow

It's the size of the box that really determines how much the sub will exurt. There is a ratio for every sub up to it's Vas. You would want to go ported and have a fairly large box. The Vas for the Sx 12's are 47.6 liters, or roughly 1.7 cubic feet. Driver displacement is .16 cubic feet, so if you build a box for about 2.4 cubic feet internally, you'd do well with 400 wrms.

if say i ran the 600.1 amp would it close or as hard as the 1200.1? if i have to i will get a diff alt which i had pretty much already planned to do sience the stock is only an 80 amp.

for what it's worth, cardomain is clearing out JBL BP1200.1 amplifiers (1200wRMS x 1 @<hidden> 2 ohms) for like $200 right now.

I'd just go with a single SX an a 1000 watt amp of your choice. I think that will provide all the "bump" you will need. Build a ported enclosure tuned fairly low (28-32 hz) and you'll have a very nice setup.

Go for that deal that KiKi mentioned.

tell me about it, i was thinkin of spendin my last bit of cash and getting another 1200.1 then after i get some more cash i could buy 2 RE XXX 12s and run 1200 each /me glares madly
Actually ive been doing alot of contemplating as of late. Im thinking about doing one of these setups.
jbl 1200.1 and 2 RE SE 12's, ideal sealed box :sub:
jbl 1200.1 and 2 RE SX 12's, large sealed box :sub: (seems like the best choice)
Jbl 1200.1 and 1 RE XXX 15", ideal sealed box :sub:
jbl 1200.1 and Adire Brahma 15", ideal sealed box. :sub:
which do you guys think would be the best?
I know they are all good sq and spl subs, i want em loud, loud enough to set of car alarms (its funny). Id like somthing that would be on par with or better than a system with 2 jl 12w7s, here is why, it may sound stupid but lol.
I was workin with a guy at my old job, and we were on the topic of car audio. He was like yeah i have 2 jl 12w7s in my car, id have to say its the best system in our town. I was like yeah 12w7s are good, but have ya heard of resonant engineering XXX subs. He was like no, it must not be that good because I would have heard of em. (hes one of them guys who thinks he knows everything). I was like nah they are awesome possibly even better than jl subs. but anyway id really like to be able to pull up next to him, crank it up and make him feel stupid. I hope ya enjoyed my little story, i just really hate know it alls.
:angry

just go for it all...two 12" XXX's with one of those JBL amps on each...im not really into that competition stuff cause im a SQ guy but to my knowledge, that might rattle his system a bit ;)
whats the xmax on a 12w7 anyways?

i think its 32 or somthin, if I get the 2 re xxx 12s i gotta go another amp asap before they sell out which means ill be broke for a good long while :(

Not good enough for me? Quite the opposite actually. They are INCREDIBLY LOUD, and I was only giving them 1/3 of their recommended power. I just purchased a pair of Rainbow Vanadium subwoofers, noit much better in my opinion. I'm going for a pure SQ setup now.
In case you were wondering, I hit 143.1 with the pair, only giving them 1/3 of their RMS power, very impressive. I'm asking $650 SHIPPED. Incredible good deal considering they weigh 60 pounds each and shipping is expensive.

(not talking to you justin, just going off of what you said :)) talking to you mith
believe me...2 10"s is not going to be quiet. They are going to be quite loud, naturally 2 12"s are going to be a bit louder. XXX's have 32mm of xmax...take a sub you have or find one and take out a measuring tape or ruler and measure 32mm outwards...its pretty shocking. Those things move a lot of air.
and yeah he's not exaggerating when he says they weigh 60lbs shipped, my 12" xxx weighed in at 53lbs, and the crate it was shipped in was over 60lbs. my mom couldnt even pick the sub up.
and depending on what type of music you listen to, if it was rock id be willing to bet 1 10" could be too much bass for you, let alone 2 10".
anyways my point is dont let the 10" fool you...dont think you have to have at least 12"...hey that one guy has a wall of 6x9's (which are tiny compared to like 12" sub) and he hit 169db :)
k bad example..

possibley better?come on man
whats the xmax on a 12w7 anyways?
its 19mm so the xxx has way more, almost 50% more.
lol id really think about it but i really like the extra spl you get from 12s
TRUST me 2 10's would be standable with MOST sub, but youre forgetting there xxx's, if you port them, give them more than 600rms, maybe 1000rms each, get a 4 volt HU, you probably will stomp on those w7's. imagine shitting on youre pals 12's with youre 10's LOL, if i were you id take those 10's from justin, you will SAVE big time.

Actually the 12W7 have 29mm, not 19. That's only I believe 3 mm less than the XXX.
