Sorry i posted this here becus at the audio section didn't get much responds at all.



Hi guys, i installed a pioneer head unit in the car and new fronts and rears speakers. when i install the front speakers these http://www.jbl.com/EN-US/Products/Pa...=1&tsT=0&ovT=1 i just connected them straight from the factory harness that was there and they work fine. Then i disconnect the battery and run new wires for the rear these http://www.jbl.com/EN-US/Products/Pa...=1&tsT=0&ovT=1 so after i finished running the wires for the rear speakers, i hooked up the speakers to test them out before putting everything back. When i plug the battery back and try to turn it on the head unit has no power but it did before i run the new wires for the rear since i didn't have any in the first place that i know off. So what could have been the problem??? I've check all the fuses to make sure, and they're all good. Also i check the harness and there was no power from the relay wire any idea why, it did have power and the radio was working before i run new wires to the rear and before i disconnect the battery.
So what could it be guys???


No power from the harness, but the harness from the dimmer is still good as well as the cig lighter so i dont think it's the ground but i did checked it and the ground from inside the deck is good.

Have you checked the fuses? The head unit should have one of its own, and then there is also the radio circuit fuse in the fuse block of the car.
