rear speakers low power factory amp? Help! Options

[joy_zze]

I have a
1999 Celica with 4 6.5" speakers and the little
tweeter in the door. I am pretty sure there is only
one factory amp in the console. For some mysterious
reason, the rear speakers are only getting about 1/4
the power of the front speakers, and very little bass.
I replaced all 6.5 inch speakers with JL audio, and
replaced the head unit with a pioneer mp3 player.
Still, the problem persists. I have double checked the
head unit installation, and all seems to be fine. Is
it possible the factory amp only partially crapped out
on the rear speakers? If so, what should i replace it
with? I don't need anything fancy. The front 4
speakers sound great. I'd just like the rear speakers
to sound as good. Should I (could I) just bypass it? Any help/hints you could offer would
be greatly appreciated, as I am getting quite
frustrated! Thank you in advance, Joy

you'll have to follow my advice anyway. Yes, it is possible that the rear speaker outputs on the stock amp died.

To fix that problem, or the problem of simply underpowering the speakers is the same thing however, and the specifics dont matter.

You need to rip out the stock amp, and buy a decent 4 channel amp rated to give out the HUGE amount of power the JLs need. This isn't going to be cheap. And then you take the preouts from the head unit (I assume it has some) to the amp.

Bypassing the stock amplifier will still not have enough power to power the new speakers- it would have been for the stockers tho, you need an aftermarket amp for those.

I do love JL tho.
