Ok, so this is my firts time actually building a legit system. I had 2 sundown sa 12's before but it wasn't enough so I'm going with Zv2 12's. I plan on running them off of a Crescendo BC3500D @ 1ohm. I have the Big 3 done in RF 1/0. The 1/0 going to the back will be replaced with something OFC. But other than that what will I need to sufficiently power this amplifier?
