advanced question for you guys on sound system Guys...IM DYING HERE! This might be long, so for those that want to help, thanks in advanced...(ive installed several systems before, so i do know what im doing...) I recently dropped an lt1/6 speed in the Camaro. The motor is a 96 and in changing the motor, i decided to put a 94 wire harness for obd1 purposes. I changed teh engine and interior harness. When I got the car out of the shop, the stock harness worked fine with the stock radio, but only on the front speakers. The guy who did my swap never connected the rear wire harnesses, and gave me the excuse that..."well, since your gonna get the car re-wired for a system, i didnt install them." I decided that when i installed the new radio, id run direct wires to the rear speakers, as well as the front door speakers. It was cake. The radio works and all four speakers are working. I had teh car wired from before teh swap for my system, with all the necessary wires running to the back of the car. I installed my amplifier and my speakers, and at first no sound was coming out of them. the amp light was green, and everything was wired properly. i thought...**** somethings wrong. I decided to remove the amp and check it on another car..it worked fine. i then made sure the speakers werent blown by connecting them to a drill battery, and the pumped as well...basically the hardware is fine. im going insane! the speakers are now thumping at a VERY LOW RATE and only when teh sound is under 10 on the jvc. next, the are thumping out of sync with the music. what do you think it could be? id hate to rewire the car, but i might be going that way. thanks for your help guys.
