I am going to use my MMATS D300HC amp (~1800 watts @ 2-ohms). The maximum overall dimensions that I can use would be 41"L x 20"D x 16"H. I am considering the following setups, if you could help me out, I would greatly appreciate it - 4 Kicker 10L7's, 4 Kicker 10L5's, 3 Kicker 12L7's, or 2 Kicker 15L7's? I assume that either would be in a sealed box, but could someone help me on the box specs? I would also need someone to build me one if possible. Thanks. I look forward to hearing from all of you.
