Ive built many boxes, with mixed success.
Im throwing this out there, to see what comes back. I can compensate for designs, if you have refs or a reputation that shows you know what you are doing. Im running 4 RE SE 12 D2 Subs off of a RF T20001BD (Benched at 2880 RMS @ 1 ohm, which it will be used at). I have a 300 amp EA Alt and 3 yellowtops, the power is there. Looking at kind of a small box however, due to the truck being on air ride there has to be an allowance for air tanks and such.
I have these max dimensions:
25" From Seat to Tailgate
36" Between wheelwells
and id kinda like to keep it below the rear seat line at 19", this is flexible, but like i said, id really like to keep it there.
Box options are basically limitless, im not afraid of a 3-4 week box build if its complicated (Like a bandpass or something....)
I just want it loud to the ear, and to get low (as i can with 12s :/ )
Musical loudness along with clarity are essential. I could care less about SPL numbers anymore, been there, done that.
I would prefer subs up, ports up. Im open to suggestions (other than subs facing the tailgate, itll rattle no matter how much sound deadner i fill it with....) Im leaning towards a bandpass with a plexi window and mounting my amp on top, as it is rather large as well.
Shoot me some suggestions, im always listening.
Car in case anyone was curious:
