needs me one of those SMD stickers with the cross over calibration and distortion detection on it. But damn that's really cool, world wide man. Did you ever think SMD would be this big?
TTT, the 4 channel has never seen power, I spoke with psi and they can build these slugs into 18's for 320 plus return shipping. would be 1500watts rms per psi.
Jasper Jig FTMFW, if you need to cut circles it's the only way to fly. Oh but will need a router to mount it to. A table saw, circular saw, jig saw, and 18v drill. Those are just the basics I use everyday.
In my Explorer I did the big 3 with 2 runs of 0 gauge for power and 2 for ground (to the front battery). I did 1 battery in the rear and was able to run at 11.2 at full tilt with a stock alt.
Try and find someone close to you, shipping would be outrageous. What I would recommend would be build it yourself, there are plenty of guys on here that can help you with the specs on it for little to no charge and if your in to audio building your own box will give you a ton of pride when your beating down the block.
