Building a box for my friend's chevy aveo and figured i would build the same box for my discovery II.
I plan on running it off a Cadence A7HC (~1200@1ohm) and he will be using a Audiopipe APSM 1300 (1000@1ohm).
The box is 2.00cubic ft before displacement. Making it 1.85ft^3. I plan on running 1 4" aero port about 12.5" this gave me ~35hz tuning according to the PSP-Inc.com calculator.
