Hey Guys and gals I have a pioneer head unit with pioneer speakers (door and deck) thunder woffers and a fosgate amp the problem I am hving is that the head unit speakers quit playing after a couple of minutes but the woffers powered by the amp still work, I have to unplug the connector at the head unit recycle the key on and off and then it will play again for a couple of minutes and they quit. I have tried to ground the unit differently but no help it is now gropunded as per the amp installation instructions at the back of the unit itself and the ground wire is grounded at the trunk where the amp is grounded. Not sure what to try next any suggestions??? Thanks John
