Interesting setup, I like the ideas. I have the Quad Cab and the back seat doesn't really leave much room to install subs into. I had thought about putting them in the floor facing up with some plexiglass over the top but that just seems like too much work with too high or a risk of destroying my floor.
Do you have any pics of your dak truckputer? I'd like to see how you have everything laid out. Also do you have a link to that amp you're talking about? I've been trying to find a good one to use. Thanks.
I've read threads where some guys with quad cabs mentioned moving their back bench seat up a few inches and out an inch or two to make room for amps underneath and subs behind the seat upper.
