This is just a shot in the dark, but I'm thinking about building this for my '04 Avalanche.
This will be for 2 DD3515E. I'm not sure on power yet, I have one of my old 20.1's in for repairs right now so that may be what I use at first. May go do a DD M4 later.
If u want you can build me one too and I'll pick it up...haha. Looks good, get ahold of me on AIM if u can cuz It looks like you may be the closest place to get a good box.
