Ok, this was one amazing build. I had less than two weeks from start to finish. This thing has 4 15" Type R subs, 4 8" Type R subs, 4 sets Kenwood 6.5" Separates and 6 amplifiers. We also installed a 3.2 audio control, 2 Sherikan batteries and 4 Farad in caps. This thing was so loud it would shake the concrete floors. Can you say amazing...
