Based on what you want, I don't see you being happy with 2 8's in a small box.

You're either going to have to re-evaluate the sound you want, re-evaluate the space you are willing to give up, or re-evaluate the level of mods you're willing to do to your truck.

First thing I'd do is get a reference point. Find someone elses system that sounds like what you want, and find out exactly what he or she has...exact model subs, exact enclosure size, exact amps. We can't work with the standard...'this guy had 2 Orion 12's in a ported box on a DEI amp, and it pounded'.

I'm sure you're probably looking for an answer sooner, but the next TR audio meet is June 10, at my shop. Last time, we had several different sub combos: 16 6 1/2's in a sealed box, a single 12 in a medium ported box on moderate power, 2 12's in a smallish ported box on fairly small power, 2 12's in a big ported box, on big power, 2 15's in a really big ported box on big power, 5 12's in a big ported box, on big power, and a single 12 in an infinate baffle, on fairly low power. I also have a computerized subwoofer modeling program. We can throw a bunch of different ideas into it, and see what comes out. If nothing else, you'll have lots of different folks to brainstorm ideas.
