I'm professional as it gets. I will show you the box when I'm finished. I'm no joke at building boxes. I'm kinda new to the under seat thing, but there isn't any special skill set required. I started this post because when I researched F150 boxes, just from eyeballing it I could tell that the cubic feet was wrong. Some guy even told me his front height was 10 inches for 3 8s, and he said "with no seat lift required". You only have 8.25 max, maybe 8.5 in the front with no seat lift. I was just wondering how these guys were coming up with all these inflated numbers? Bobby, I just made a box for 2 15s for a Suburban. Pics below with 3rd row in, and you let me know if I still need a professional? He didn't like the black box on the right because it wasn't hitting any lows, and it was installed improperly by a professional. They didn't even use the speaker terminals on the box, instead they drilled 2 big holes in the box under each terminal cup and ran the speaker wire like that. The box was leaking air in about 5 different places.
