ok...i want to build the biggest custom enclosure i can fit in a regular cab. i was thinking of keeping them not too deep, but making them almost up to the rear window in height. what i want to accomplish is mounting 2 MTX Thunder8000 10's in there, so i need depth, but only just enough to fit the subs in there. building the box is no problem at all, i just really need dimensions. i kinda want them to look like the enclosure clayton posted in the "reg cab enclosures" on the second page - theyre purple - about that tall, and that deep. also, where can i buy the carpet to put on the boxes? any help would be great...oh, and what is a good amp to power 2 of the 8000's? i was looking at the alpine MRD-M500, will that be strong enough to make some noise?
