hey guys i just joined the forums after lurking for ages so hi i finally needed some help after not being able to figure it out. so in this pic i have my amp set up out of my old car, i know where everything else goes besides this black wire. As you can see it goes into a REM socket which is linked by both amps. the wire in my hand is the other loose one which is very long, almost as if it were meant to go to the front of the car somewhere. do you guys know where? Thank you. Some original photos have not been recovered yet.

If the other amp isn't hooked up to the head unit It goes to the back of that mate.

The REM(remote wire) on your amp goes to the REM(remote wire) on your deck(head unit).

thanks guys, found it all working now Some original photos have not been recovered yet.
