New Subs / Amps - Need Box Help :]

[Cynner]

Hey guys, back again. Just wanted a bit of help. Order a bunch of new stuff.

Cadence ZRS-8000D Class D Mono Block Amps x 2

Cadence ZRS 12-1000-2 Subwoofer x 4

Now I really want to make a ported box for these. They'll be running @ 1000RMS / 1ohm.

Also wanted to know, I could just get 2 15" DCX15-1500-2 which would be better? 4 12" subs or 2 15" subs? The 15" run at 1500RMS

Here's the room I have to work with, going to wall my car in hopes I get big numbers.

48" Wide

20" Deep based on the layout of the car though 20" max unless the box is not as wide then I can go back as far as I want.

36" Height

It's a Hyundai Getz as well which most of you might not have heard of.

Thanks guys, really hope for a reply! Going to start project this weekend. Feel free to throw in any comments about the subs if anyone knows history or has used in the past, or might know of better. I know I could probably work this out my self but really want some help from people who know what their doing.
