Tune it to 42hz, that way it will still play music on the street, as well as pull a decent SPL score (for the quality of the equipment you are using). You should be in the 140's with ease!

I'd agree, that box is a bit big, maybe go with MTX's specs on the box if your not planing on doing big numbers

for SPL, go with something like 2.25 cubes and tune it accordingly to what the car peaks at.
Or 42hz as I recomended above-that would be an Ideal starting point.

why would you even bother asking for advice if you're gonna do what you plan to anyways [img]graemlins/dunno.gif[/img]

pretty much everyone agrees that the box size is too big and you still insist on a using manuf. spec

now, ATOMIC Caravan gave a good suggestion... start with a 2.25ft3 box and just play with port tuning. In spl, bigger does always mean louder, other factors also come to play and with the power that was suggested on using, then a smaller box would get you where you want

anything over 2.5 cubes for a single sub is too big!
