So i just started my build this weekend(tue-wed)for me. The build is simple, not to much to it. 2 Sundown Audio SA-8's Dual 4 ohm 1 hifonics brutus 1200.1 1 xs power d1200 batt. That's all the new stuff i am getting. I already have 1 d1200 under the hood and a 300amp custom built alt. This is going to go with my 2 sets of massive audio rk6 component's and my massive audio 4 channel with a pioneer touch screen dvd3100.
