OK!
So i installed my cd player in my 929, it has a factory AMP in it. So i hook up the radio, it comes on.. But i get no sound. Even the power antennae went up and down. But no sound.. I read that i will have to bypass the factory amp to get it to work, by running wires directly to the speakers. But i know there is a easier solution.. i dont want to pull up my carpet/seats etc.. for this. is there a harness, is there a way to wire up the factory amp to the aftermarket radio?

BTW, the car has a Cd changer/steering wheel controls also if that means anything
