I see that the recommended enclosure is 2.0 ft^3 tuned to 29hz for the 12" D2. I want about 50/50 with sq and spl...so yeah, i want LSQ . What difference would a bigger box (about 3 or 4 cubes) make? What should I tune it to? I will be running 1000w to it @ 1ohm. This is my first car audio system so bare with me here . I appreciate your help guys! Thanks, -harrison
