Thats what fawking matters! And bass mechanic, why are you jumpin on my case? If its my fawking opinion, it my fawking opinion! You want to make me a sick ass box for $50 then we will talk... Thats how much it cost me to make my CUSTOM box for the back of my hatch! And as far as shape and all that goes, I talked to JL derictly and made the box to there specs! Im not positive, but I think they know what they are talking about (no sarcasm)... All Im sayin is in MY OPINION dudes 10's will not hit louder than my 12's. Im not tryin to be a BADASS or put anyone down. Im sure they sound great! and Im sure with all that experiance you got bass, you can make the PERFECT boxes. However Im not fawking rich! I am however very pleased with the sound quality and quantity of my system....THE END....
