I'm looking for someone with some expeirience with ssd's I have an old caravan and looking to do a grounpounder setup. 220 amp alt 3 deka's in the back 4 run's of 1/0. I'm going to run 3 18" ssd's in around 20 cubes at 34hz off an ap3k at 1.5ohms I'm sure i can support the amp at 1.5 with my electrical. Does this sound about right subs up port back around 300 to 320 inches of port space.
