[QUOTE="Saint211, post: 4873597, member: 564903"] Some of the older europeans and older cars have funky wiring. Ive even heard of a few that use a positive chassis. Common ground systems etc. It has nothing to do with a non-steady voltage. Show me a car with a complete steady voltage... lol I'd try running 12 v + (yellow wire) directly to battery positive, then ground(black) directly to battery negative, then go to the ignition lines, test for a switched 12 v (accessory) and run the accessory(red wire) from the cd player there. The rest should be fine, make sure no speaker lines are shorting on each other too. This effectively avoids as much of the stock wiring as possible for the power connections. How does it lose power? while the cars running? with the key in the on position? Or does it lose memory when shut off? Does it cut in and out? or just shut off? I need more info [/QUOTE]
