Well, I finally got this stereo thing figured out. Bypassed the factory amp and everything is good. The only problem I have now is that the positive battery post sparks when I put the cable on. It does not do this when I disconnect the radio. I followed the install directions, soldered, and used heat shrinks to make sure it stays in good condition. I don't see what the problem could be with the radio wiring harness, maybe someone can help me out? Thanks.
 
There are many circuits which have constant 12 volts to them. Any one of them could cause a draw.

Good luck.

That, and the fact that the factory amp is weak compared to the head units that are made these days. I think its like a 35w amp for all the speakers! :nice:

Most of them are 35w max! usually around 11 to 14 rms. Most companies put the MAX wattage on their product. Just like a little jensen amp does not up out 5000 amps.
