Thoughts? Use the 2 small batteries under seat to power amp and under seat subwoofer box. Pull signal from 2 wires that plug into oem sub. If this could be done you could keep all the wiring under the seat and not have to punch up thru the firewall.

Under the carpet in the rear seat area is two plastic caps perfect for running wire into or out of the cab. I run all my wires to the bed for my battery. Just another option for you. But if you have the space in the cab better off honestly. I need a good bit of batter for 10,000 watts.
