I need dimensions for a SPL (loud bass or loudest as possible) box if anyone can help me out for my L7 12" dual 2ohm 06 model pushed by kicker 1200/1. I want it to be ported, tuned to 30-35Hz (higher better, I think for loud w/o blowing sub), and be in the dimensions of 14H x16D x34L inches. I have that much room and only want SPL (Loudest bass, guessing SPL stands for loud bass. I would like to have just 1 port in the front or side and this is going to go in the back of an extended cab truck for 1 of the seats. The box has to be all wood (3/4-1.0"). If anyone can help me with a design or send me a link to buy a box that is close to that, please let me know? I will also buy one from someone who will build it for $100 total with shipping to 77554. Thanks a lot Brad
