Extended Cab boys, School me on how to get loud in a Truck 4 12"s

Well I bought a ex. cab 99' Z71 and I need some enclosure help..

A little about what I expect, I'm running 4 12"s with 350RMS going to each one (subs are RE SRX D2's) Now I have a TON of room to work with..

so how to you get loud? subs facing back seat and port facing up on passenger side is what my ORIGINAL plan..

Shed some light on the situation. I Plan on tuning in the 32hz range, I LUH ME SOME LOWZ.

But I know its usually 10% equipment 90% install, so what kind of box will kill the lows, sound good for daily, and be pretty loud?
