The point wich has been made (and I agree), is that many modern "high power" car stereos use a bridged output on the amplifier (also know as floating ground). If you tie the negative leads on the output together, at best it will sound like crap.. At worst, you will damage the stereo unit. My suggestion is to run new wires.. Leave the stock harness alone. --- Video Bob <videobob@xxxxxxxxxxx> wrote: > The harness has 9 wires, I will break them down for > you. > > 1. Constant 12 volt > 2. Power on 12 volt > 3. Ground > 4.
