this is on a piece of plywood on the back of my seat. the wires go through wood and behind seat carpet.

sub box is angled on the back to fit right up against the amps and is angled in the front to be parallel to closed hatch glass.
im gonna do it over again with a different setup that i am working on now as i mentioned before......think i'm gonna use fiberglass and matte the s$$$ out of it.
