You need a power wire(A small gauge like a 8 or 6) to run from the power slot on the amp to the battery.

You need about the same size wire to run from the ground in the amp to a good ground bolt in the back ie. a strut mount.

A smaller gauge prol 12 as a remot wire to tell the amp when to turn on, run it to a fuse that only workls when the car was on.

And RCA cables hope that helps
