my max dimensions are now
19 H
19 D
42 L
i would like to either make my own box and buy plans from someone on here. or just buy a box from someone on here. my sub is a 15 inch omega 2000 watts (rms)
i would like to get 3.5 ish cubed tuned to around 32 ish

if i could shorten up the length to maybe 32 that would be great but not nessisary (sp) i would also like sub facing the cabin and im not to sure about the port yet.
any ideas/ help? this is going in the trunk of my car btw
