I need a wiring kit to power a Kicker KX 800.2 Amp. I know it needs to be 4 gauge, but I I don't know how many watts it will have to be. It will be pushing 2 Kicker Comp VR 12 inches. 2 x 400 @ 2 ohms. It'd be nice to have the fuseholder all ready attached. Anybody have any suggestions for a good kit?
