Factory amp or low impedence factory speakers
I would pick a new HU. for as far as I know JVC comes forth of the same factory where sony's been made, so wouldn't get my hopes up too hight that fixing the problem will hold too long

To save you some money.
Trask the rear output.
Make the rear output as the front. Swap the Pioneer currently from the back. Trask the stock speaker or just use it to cover the speaker hole in the back.
So now you have the HU run 2 pioneer speaker in the front and the amp run the sub. That is all you need. A lot of people don't use rear speaker (and they refer to it as who need rear fill.)
Okay although this forum has audio section, but only a few people know about car audio inside out. Most of us are just like you either has no clue or with very little. That is the reason the sticky advice you to get help else where that didicated to car audio. Eventually you will get the answer (maybe), but it will take time and probably wrong answer as well.
Thanks for the help, still havent had any replies from the other websites in the sticky...Good idea MAtrixpc except that the rear speakers are 6x9 in a box (SUV) so that wouldn't really work to swap them out with the 4x6's in the front. although I could just spend a little bit of money on some components for the front, which would be cheaper than a new HU, and forgot about the rear speakers like you said. But then the rear channels could go out tommorow with my luck...
Dont swap the speakers, swap the output of the deck. Hook up the rear speaker output of the deck to the front speakers. Do not hook anything to the front speaker output or the rear speakers.
My guess is you will have the same problem.
You need to run new speaker wires from the deck to the front speakers. Do not use the factory speaker wires
What kind of car is it? Does it have a factory amplifier?
Its possible, and a lot cheaper to test than buying a new HU.
