3 Sundown Audio 8" SA-8v.2s under the seat would be the best setup for the supercab & supercrew without having to raise the seats. My buddy dud 4 8s but had to raise the seats. Digitial Design makes a better 8, but for $400 each versus $185 each for SAs & the SPL is barely any different. 1 8" SA-8 can hit 150 DBs. SA-8s only require 0.6 cubic feet ported & only displace 0.1 cubic feet, so you only need 0.7 cubic feet total per sub for a ported application. A custom built box negating the bracket on the 60/40 seat setup would net you enough room for 3 8s forward firing. Power them with a good amp, at least putting 500w rms to them each & you'll have a system that slams. Upgrade your Battery to an XS Power D2700 battery at least (I'm doing D3100) & upgrade your Big 3 with 1/0 gauge wire & use 1/0 gauge wire for the amp install & you'll be set. This will set you back roughly $1600.
3 SA-8s: $555
Hifonics Brutus BRZ2100: $280
50 ft 1/0 gauge wire: $130
Box Materials: $100
XS D3100 w/side mount term: $400
Misc: $200
Also depending on if you have a stock radio or not. I'm getting mine with the stock navigation so I'll go with a digital sound processor, something like the JL Cleansweep, which helps tweak your sound perfectly. That'll run you an extra $2-300.
