Today i was kinda tinkering with my truck that i jus bought. It already had a pioneer deh-p3600 and speakers hooked up to it but the speakers were kinda messed up they jus didnt sound good. So i took the headunit out and started messing around. I had a bazooka tube from a previous car so i decided to hook it up. I had everything going then the sound jus stopped. I checked all the wires and everything was connected but no sound. I changed speakers jus to see if they were blown but it was the same with 7 different speakers. When i hook up the bazooka i have to turn the sound all the way up and i can still barely hear it. I cant hear anything from the regular speakers. Whats wrong? I think the wiring harness that came with the pioneer headunit is messed up, where can i buy a new one?

theres a couple things that will do that. one is you had a bad ground connection to the stereo so when you turn it up the amplifier in the stereo pulled power and didnt get it. this causes the amp to die and or be destroyed. it is acompanied by dimming lights on the face of the stereo at moderate to high volume levels. the other thing that may have happened is the speaker wires shorted out somewhere and destroyed the amp in the radio. you will probably have to have the radi replaced or repaired. that stereo is about three years old. and it might be cheaper to just get a new one. the 3900 mp is equivelant and actually has a few more features and will still give you the sub controll and high pass filter.

You may have blown your finals in screwing with the wiring. You may still have audio out from the "line out" connections from the preamp as they are common ground, but the finals are by-amped or floating ground. If you got those pairs mixed up or hooked to each other or to ground then you may well have fried them. That is why that is an 8 wire system and none of them dare go to any other, cross wired, or to ground.
And as per above, if the cross wiring or short still exists, the shutdown circuit may be on and may have saved you. UN-hook every speaker connection and then using only one speaker, hook it across any pair (they are color coded) and check the individual outputs.

It's possible that one of the speaker wires is touching bare metal (grounding). This will shut the internal amp in your radio down every time. If you think it's the harness, check here:
