I am looking to design a box that will net 1.5 ft^3, and be tuned at 34 hz that will still fit under the rear seat of my Silverado.
I have come up with some rudimentary dimensions that will provide an estimated 1.68 ft^3 gross, and 1.53 ft^3 after sub, but before port.
The RL-p 12" displaces .15 ft^3
From the top: W=15", L=32"
From the front, from left to right: H1=7", H2=9", L1=12", L2=20"
You should be able to interpolate the rest...
