Hey everyone i am interested in buying a Fi BL 15 and i have a chevy s10 ext. cab. My approximate space is 48" length, 17" depth, and anywhere from 17" to 28" height I have a few questions and would be happy with any answers anyone can give me....

1. I am thinking about building my own box at 4 cubic ft. tuned at 32 or 33 hz, but i do not know how to correctly port a box. anyone that could help talk me through that would be appreciated.

2. An option i was thinking was facing sub forward but i didnt know with 17" depth if i would have enough space between the box and the magnet. (Mounting depth for Fi BL 15 is 8.250") Also if i faced it forwards my depth area would shrink to about 14.5"....

Like i stated any information about any of my questions would be appreciated

Most of the people I have seen on youtube with BL or BTL in a s10/sonoma, have their subwoofer firing up, and the port also firing up, with the port on the drivers side, sub on the opposite side. 32hz is a good tuning too.
