Well I was going to get my box built elsewhere but I decided to try it myself. I can design it myself but I am clueless as to how to tune it... I want it at ~30 herts. I'm gonna build the box 16"H 36"W and 20" deep, it should be around 4.5 cubes. Who wants to help me with my port? :naughty:

some where near half the Sd of the sub. i always tell people to call the company they got it from though; they know what boxes work best for their subs. if their customer service is half decent, you should be able to provide them with the maximum dimensions in your car and have them tell you what the dimensions of their box should be.

Your sig is like a foreign language to me... but I'll try :)

BTW I'm out taking my door panels off and trying to figure out how I could get XXX mids in there, thus I'm responding slowly.

go 3" x 15" (45"^2 of port area, and so the internal height will be 15") and figure out how long the port length will be, then i'll design the actual box itself for ya so we can measure the trunk and everything

I have the measurements, had to take out the amp rack to get the extra 3 inches making it 16" tall. Well let's build it this weekend or something then man. I just need to buy the **** and I can do it any time once I have the plans made.

Edit: So the internal height can only be 14.5 in...
