2 DD 3515s would be good on a 3500 also or sundown 3000

For the 3500 I would upgrade the under hood battery and put 2 large batteries int he trunk with a nice alt and you should keep your voltage up.

wat numbers are you hittin now with your current system

It'd be alright... might still keep it facing the rear though - try it both ways. With the backseat down it'll be louder in general.

Two HDC315's or 18's with an AQ 3500 would be just right for your goals. Advice is to wall it. Mount them in the back seat gap, seal it from the trunk. Basically what you're doing, except seal the front of the box from the trunk with another piece of wood. That's the best you can do, and the trunk won't give off that annoying rattle that everyone with cheap shit has.

so basically mount the subs behind the seat seal off the edges and use the trunk as the box? or seal it the use the trunk space to build as big as possible box attached to the face plate ?
