schrei - I am using this woofer Pioneer TS-SW2541D 10" 4-ohm shallow subwoofer at Crutchfield.com.
Amp is an alpine - Alpine MRD-M605 Mono subwoofer amplifier 400 watts RMS x 1 at Crutchfield.com
I'm overpowering it a bit, but only cause I plan to add/hide another 10 somewhere.

I don't think a 10W3 would would. It would fit yes, but they require a lot more space than the shallow mounts.
That's why I figured I would offer the box to everyone, since JL makes one but its $500. Mine also take about a day or two to complete, so there's a lot more to it than some might think.

Offering them at 100 plus shipping. I just had someone ask about shipping to upstate NY, from here in Miami, and it was about $17 for UPS ground.

DKL - I put the amp on the left side, up against the carpeted interior wall (I don't have DSP or NAV). Perfect spot for it. Theres some videos on youtube as well if you wanted to know how to wire it all up.
