So you guys are saying I should go with 2 12" CVX's sealed?? Im gussing I should go with them because they do better sealed than the L7's correct. I've also been looking at some other brands like audioque and maybe Fi. So with the space I have, about 3.8 ft^3, and the power, Power Acoustik 2400db ~1500 rms. What single or multiple sub combo would you guys suggest. I wanna stick with 12"s or smaller cus anything bigger and its gonna be too deep. The max mounting depth ive got to work with is about 7". Thanks for all the help so far.
