So here is my install plan and parts i am using. Please give me tips on wiring etc or if anythign im missing or something may go wrong.

Using factory amp input signals for front bass speaker for my sub signals

Using a 400 watt camp with a 30 amp fuse in it. Connecting the remote wire to the 12 volt wire in the boot. Connecting ground wire to chassis

Bought a monster install kit for a 500 watt and lower amplifier. Includes 80 amp fuse, 4 gauge power wire, and remote...ground wire, etc.

That sound alright?
