This is great guys, thank you very much.
Chad, I'd love to stick the sub back there, but, it's a one-piece sub/amp combo, and I don't think it will fit in that area. It's nice that it's all in one box, but it does take up a decent amount of space. Should go under the rear of my drivers seat, might take up a little foot room in the rear passenger area, but, don't usually have riders back there anyway.
Here's the sub I got:

By the way, I'm wrapping up my floorboard repair... what a nightmare that was!!!!
