level 5 dc 15 box help

[T2bumper]

i am starting a new build in my aveo, i know its a small car but i want it loud

i will be powering 1 level 5 dc 15 on a rockford t2500

i will be facing the sub and port forward and sealing it off, the dimensions i have to work with are 38 wide x 28 tall x 24 deep

if possible i want a square areo type port

lastly i need it tuned around 30-32 hz

thank you for any input it is greatly apreciated!!

Since you are under-powering the sub I would suggest a box slightly bigger than recommended (3.5 cu.ft). So 19H x 38W x 18D with a slot port with height 17.5, width 4 and length 35. That will give you a 4 cube box tuned to 32 hz.

Larger than normal will help with the lower tuning as well. Make sure to seal off well, including the rear deck.
