I need help with my car soundz i got 4 speakers runnin of my sony xplod head unit and a sub runinn of my amp. It was going fine until 1 of my m8s disconnected da rear speaker wires and put dem on 2 da amp positive n negative channel. He started da car n dear was sum beepin noises and now their is no sound comin out of all four speakers but their is a little cumin out of da sub. The wiring is the exact same as it was when it was running good. Does any body know what is going on here?????
Wait, he connected the head unit speaker output wires to the output of the external amp? If that's what he did, then I would suspect at least a fried output IC.
Obviously not the exact one but similar. It could be anywhere on the main pcb (printed control board). Sometimes if you fry it badly enough, you can tell which one it is because it will be blackened or melted in one way or another.
There could be other problems as well, but for now the output IC should be the focus.
hiya mate did you solve the problem with ur sony, as i have the same problem mine all speakers went off out the blue and never came bak on when i connect a diffrent headunit in it gives sound any suggestions on what excatly it could be and much you you reckon it would cost as my stereo is not under warrenty cheers
