i know... another access cab sub thread! check it out though, i think i've come up with something really unique.
i took the concept from the jl stealth box, but adapted it to fit a jl 6w3 in a ported enclosure. the rear seats still fold down normally!
i cut out the entire middle of the center console so that the box slides in. it is anchored to both the console and the floor bracket so that it won't move. this deletes about 90% of the center console but still leaves some storage, as well as the cupholders. i can still keep pens/paper, wallet, candy bars, misc stuff in the console.
it's .25cu ft, made of 1/2" mdf, with a 16" x 1/4" slot port that follows the top inside edge. i used a box design software to calculate the port needed. initially i was skeptical of a port that is only 1/4" thick, but there is zero whistling. i've got some electrical tape covering the opening because the fabric looked a little ragged, i might look into something cleaner. the covering is velour from joanne fabrics in the exact same grey as the truck interior. a grille over the woofer makes the whole package virtually indestructable.
sounds amazing, punchy and low! the rockford fosgate 150w rms under the driver seat drives the 6w3 like an absolute beast. the end result is definitely comparable to an 8", maybe even a 10! i've had 10's and 15's before, which were overkill. i honestly think this is perfect for the interior of a truck.
