6.5V preouts cause problems for some amps?

[muddybear]

I was planing to pick up a Premier 860mp which has 6.5V preouts. And I was thinking about getting a JL 1000/1 or a Phoenix Gold Xenon X1200.1. how do I know if they amps will work well being powered by 6.5V preouts. I've heard that can be bad. Are there any Amps you would recomend?

I know that the JL will handle that with no problem. You'd have to look at the PG's specs and see what its maximum input voltage (on the RCA's) is.

To feed the amplifier the highest it can handle is ideal. The JL goes up to 8 volts.

I own a x600.1 and an x100.4 with that same headunit. The gains are turned up about half way, and I still dont get distortion at max volume. I believe the gains go from .2v to 8v.

By the way, go with the Phoenix Gold. The JL is good, but not any better than the PG which costs a lot less. About $250 less at sonicelectronix. If you think you will get an extra 250 dollars worth of sound from the JL, you are nuts. http://www.sonicelectronix.com/item_2749.html.

Wow, umm...no? i wouldn't even almost put PG on the same level as JL.

Were not comparing Boss to JL, were comparing two very good quality amplifiers. My whole point was, if there is much difference between the two, it sure as hell isnt worth an extra 30% in price. If your goal is to have the absolute best money-is-no-object stereo system, then buy the JL. The new Chevy Corvette beat the new 911 in a comparison test done by Motor Trend recently. Why is this relevant? Same idea - neither one can outperform the other by much, so it may not be worth the extra $30,000 for the "Porsche" nameplate to most people.

Your analogy of the Porshe and Corvette may have more merrit if the newer Corvette wasn't better than the older models :)

My point is that PG doesn't produce the quality of amplifiers that they did in the mid 90's, so the JL is really in a higher class.

For the record, I would go with the PG as well because I can't see spending that much more, but if money were no object I would get the JL. It becomes a matter of balancing preferences with finances :bigwink:

If you think the Xenon amps are not as good as the old ones, check out this thread. http://soundoff.phoenixgold.com/viewtopic.php?t=5791&highlight=x100+4+review

thats a great review

[Renegadesrun]

From a board with its head up PG's bum, but yea, great review.

[GlassWolf]

actually a lot of people there are rather disliking of PG.. more and mroe so since they shut down the general discussion forum. There's a lot of PG flaming that happens there as well as overhyped worshipping. Most of the good users are leaving that forum now though.

anyway in regards to the Pioneer and 6.5V preouts, from what I've seen they are actually 4V preouts, that produce 6.5V with the boosts turned all the way up.. so for normal operation you'll be fine, getting a 4V signal with boosts leveled out.

yay this got off topic quick :words

I think I got the thread pretty spot on.
4 volt preouts work with nearly anything sold in the last 5 years or so.
I think he'll be fine with any amplifier he picks if it's new.
the pre-outs are only 6.5V at full volume, with the pre-out levels maxed out.
levels should be kept at zero or near it, and volume generally shouldn't go past about 80% of full anyway to avoid clipping the signal, so he'll be fine, remaining at or below 4V if he does these simple things listed above.
a JL amp takes up to 8 volt inputs anyway though so that'd take anything up to and including an Eclipse head unit with 8V preouts.

[Renegadesrun]

There are quite a few 2v amps running around, so there is just cause for concern, but not if you pay attention to what v the amp will take. Anyway. That may be where he heard whatever it was that made him start the thread. In which case, yea 6.5 would not be good. Memphis and low end Arc come to mind right of the top of my head.

The JL is a substantial amp. One of the few i would install and never look back and wonder.

WRONG! There quality is still there, just getting a bad rap right now w/the 1st batch run, which is now not a problem. The amps are still over built as hell as the JLs are, but not as "overkill" as PG.

[muddybear]

which do you guys think would give cleaner sound quality, the JL or the PG?

[smgreen20]

Not because I'm biased to PG, but a forum member on another site knows his amps (inside and out) he's buliding his own. He's got his degrees and he had done a review on one of the JL/ amps and a PG X200.2, the quality of the PG was a HAIR better. In parts used and quantity, meaning they didn't skimp out if it would "get by".

[muddybear]

thanks. I was going to go for PG cause of the price, but decided to go with JL. I prefer the way they look, and since I figured I can't really go wrong with either one, I decided to go with the one I like better. Another reason I chose JL is the fact that I used to have a component set up front and loved the SQ from them.
