Re: Subs and Amp?
I think most types and brands of subs and amps will work in your 04. I know guys have used 10" and 12"'s in the trunk with a custom box. I think 10" are the tallest you can go sitting upright, and that was in a coupe trunk, not sure if the verts have less room.
I think you can wire the subs right into the mach 460 (I'm guessing you have it since you have a premium vert.)...not really an audio expert.
I know a guy that put an Alpine Type R and a MRD 300 amp in his 01. He was pretty happy with it. Definitely gave him the bass bump he wanted.
