thats a pretty damn big box...my btl box will only be 3 cubes after dis and at 34 hz btl like low tuned boxes also what kinda of power you throwing at it... if you thrown lots of power that box is def to big and you will take a chance at bottoming it out
not really worried about the price if the dc will be a better sub i have a 15 hdc3 in my other car and like it but im wantng to try dc but if they are about the same then i will go wit the hdc3 and whatever sub i will get will be at full power this is a rebuild so i dont really have anything for it but wires so far
it will be all professionaly done and they will put the box in through the backseat and the sub will be facing the cabin of the car and will be completely sealed off
