The sub I have was a prototype that I got my hands on. It's only 1 sub that has 4 voice coils on it. This will b my 1st build with a sub this size. I already have the 0 gauge wire, 300 amp alt, Kenetik 2400 batts r on the way, I just need an amp 2 handle this sub. I'm pushing a MA180XL but it's only 1600 watts. It's good 4 a lil bump but like a junkie I need more than that.
