Going to be going in my '92 Bonneville. Going over box design in my head. Single 15" Kicker L7, Dual 2ohm.
Wanted to know how good this sounds:

36"width X 17"height X 18" depth.

Comes out to be about 4.5cubes after displacment, tuned to 34Hz with 50sq. in. of port. Does this sound good? Going to be running 1200-1500w to it.
Another question, my car's rear seat has an armrest that folds down, opening up into the trunk... the opening is 9.5" high by 7.25" wide. Would I notice much of a difference if I were to do sub/port firing towards the rear seat, with the armrest down, opposed to sub/port back?
Heres a pic of my trunk:

That should be a good size for daily driving and playing music. As for firing directions, I cannot give a definite answer because I have never worked with a trunk like that. All that I can say is try both ways.

Yah... I have chatted with him. The box he had was a bandpass, and I thought of going that route, but figured it would be easier just to do a simple ported box.

Do you think 50sq. in. of port would be sufficient, or should I shoot for a little more?

i have read that 12-16 sq in of port area per cube is good. i think i read that on ROE
