Well a better amp and subs would be a good upgrade in the future, but really man your not going to find enough airspace under the back seats to hit hard, the box is what will make the biggest difference. The bad thing is there are only a few ways to get that airspace and most of them don't involve that back seat haha

so far...

well the box comes 3" up from the top of the well and is fiberglass molded to the botom of the well. also 2 ports that are 1.5"x4" wide and 15" long roughly.

Yeah but I'm talking about total airspace, a ported boc for 2 normal sized subs (not slims) USUALLY needs at least 1.5-2.5 cubic feet per sub... It also depends on the sub, but I don't know of many that need less than 1.5ft^3 airspace in a ported box, and there is definatly not 4 cubes under the seat

I'd do 4 SA 8s in a custom ported box under the seats...

I still think that even for 4 sa-8's that's a little too small. Maybe two 10's but idk. I took the seats out of my quad cab haha. You can maybe do that too and build a box for two bad ass 10's back there and make the box short enough where you can sit on it still.

Hell yeah man, make a project out of it, find a friend who can glass and try it out! That's probably your best bet keeping the seats in without cutting a big hole in your bed lol
