I have a brand new never opened amp installation kit by Rockford Fosgate for systems up to 500 watts. The wires are 8 gauge. This includes everything needed to install an amplifier. It includes power cable, ground cable, AGU fuseblock with fuse, crimp spades, remote turn-on lead, and hardware. I bought this intending to install an amp and sub but never have gotten around to it. I bought it as Bestbuy for $50. Will sell it for $25 + shipping fee.

 

Just to let you know, you would still need a set of RCA cables to complete the amp install.
