2005 chevy colbalt
Hey guys, so i messed up thinking i could install a aftermarket head unit into an 2005 chevy colbalt without a harness like any other car. So i tried hooking up the aftermarket head unit and it turned on but no sound came from the speakers. i hooked all the stock options back up and now my stock unit comes on and will play a cd but no music comes out of my speakers? did i blow the amps some how or something? need help!!!
