sub up, port back is good and you could tune the box to 34 or 38 hertz. your not going to know which one is louder until you put it in the car and meter it cause your car might change your note. most of the time for me it's not even an audible difference tho if it's just 4 hertz.

so what kind of cubes could i get out of the dems i just set??? thanks for the help you seem to be the only one willing to help considering i need design by morning

Last time I checked cavaliers peaked pretty high, so you'd probably want to tune a lot higher if you're going for spl. If this is a daily setup, 34hz is fine.

ok so ill probably just do two boxes but I need a design for a 38 hz box
