Stereo Trouble
Just starting off I want to say that I don't know much about automotive stereo applications, but I know how to install a head unit or amp or speakers. I just don't know how to fix much, or how most of the system works.
I'll describe my current system before I state my problem, just for clarity. Note that the car is a 1993 Mustang LX.
Head/deck: Pioneer DEH-P7300MP, about 3 years old, cd player and ipod input
Stock amp
stock front speakers/wiring
Dual (best buy) brand barely better than stock 6.5" rear speakers inside cabin.
As you can see, it's not a complex system.
My problem is that I get nothing from my left channel, just a pop when I plug in a speaker, even with the power off and the key off. After a few minutes, the left channel speakers get hot on the magnets, almost hot enough to burn my hand. I don't get this from the right channel, which works perfectly. Has anyone had this problem? How do I fix this? My only idea is that perhaps the people who installed the deck when I bought it didn't bypass the amp, but I wouldn't think it would make the left channel disappear and make the speakers hot. How do I go about bypassing the amp? Would that solve my problem? Thanks in advance.

You could have a dc current going through the speaker due to a short. Take the speaker out of the car and use a 9V battery to see if the noise is almsot the same.
If the coil on the speaker is shorted against the magnet this could also do it.
Remove the speaker, trace the wiring, watch for any frays or missing insulation. There could posibly be a dead short in your stock amp but I would check the wiring first.

Well, I hooked up a speaker right to the head, bypassing everything else, and it seems I get the same problem at the head unit. So there's a short in my head unit, and I guess I'll have to buy another sometime. Just for reference, how do I bypass the stock amp? Do I have to buy an adapter, or can I crimp the wires together at the amp?
