Hey... new here but have been living car audio for close to 10 years and 5 or 6 completely new setups in 3 vehicles. I'm stumped as far as solutions for a box for a new truck I just got. I want to retain the bench seat in the extended cab because of passenger room but I want to get my 12"s in ASAP. I've thought about an under the seat box and raise the seat up about 4 inches so I'd have about 10" to work with but that's a last resort. In my other Ranger that just got totalled, I had 4 12" Perfects that took up the whole ext. cab with the box and the glass work and amps but I don't have that kinda room anymore. I'd love to just say heck with the seat and build this massive box, but I'm trimming down for this vehicle. Any ideas or suggestions from anyone who's had an F150 or has done work with one? Thanx.
