yeah it was jsut needing a ground.... i jsut didnt want to send the wrong voltage or something if it needed it.
when i asked a guy at best buy he avoided me like the plague....
i then asked a guy at circuit city casually jsut saying "how are you able to demo them without a parking brake in there.. .and he simply said to ground the wire
... so i did
..stereo kicks all sorts of ass now
