Could someone assist me with a box for this JL Audio 12w7. I have a single cab truck so what I want is something like a blow through. So what I had in mind was doing a bandpass box with a port into the cab. I called JL Audio and they recommend 1 cu. ft .for the sealed box, 1 cu. ft. for the ported box and 30 sq. in for the port and for it to be 23.25 in. long. Could someone come up with a box design with these dimensions? I have tried but just can't figure it out. Any help will be greatly appreciated. I will be pushing the speaker with a JL Audio 1000/1 amp. The dimension for the bed are 19" height, 48" width and depth can be whatever.
Thanks,
