Nothing yet, I'm just getting started on my build. I'll be running four Fi BTL N2 18 D1's off of 4 DDM3's if I can find another one and a DDA4 & DDC4a running two sets of Alpine SPX-13 Pro's, which I'm sure won't be able to keep up with the subs. 2 XS-3100d in the back and XS-3400d under the hood with five runs of 1/0. I'm sure I'll need to add some alts, just have one 250 amp right now.
