Also did a center console, as my middle bench seat was shot. Tore the seat apart, saved the frame so that I would have good, solid mounting points for the console. Have two older Powerbass S-10s (single coil) in a 1.2 cu ft sealed enclosure, planning on running them with an old Kenwood 250w monoblock for midbass, most likely from 60 Hz to about 120Hz. Want to anchor the front imaging, I did this in my old Tahoe, and really liked the way it sounded.
The base, with all my junk underneath. None of that will be in there, will be mounting two of my amps underneath - that's what the cleats are for, to raise the console itself up.
Front section of the console, sealed enclosure for the two 10's. Not ported, I have those ports sealed off with the "puck" from the cutout, they make great cupholders, can easily hold a 32 oz bottle of Powerade. The one hole was off by about 1/8th of an inch, but anal retentive mind wouldn't deal with it, so I ovaled both holes, and built out the holes a bit with some thick marine-grade tape. Problem solved.
Two tens, wired in parallel for a 2 ohm load.
Console pushed all the way forward, matching the contour of the dash. You can see how it is elevated off the base (still have all my junk in there during the test fitting, since removed and filling up the storage space).
Center console storage, fits tight with the forward enclosure.
A couple of side trim pieces, don't want everything to be square and boxy. The holes in the bottom enclosure are there for two purposes - 1) allow ventilation for the amps, and 2) putting blue LEDs inside, will get a nice glow radiating out onto the front floor.
And finally, the lid for the storage. It flips open towards the passenger seat, there's enough of a lip where it extends over the curved trim piece so that I don't need to build in any handle or finger pull.
I have a roll of the same carpet that I used for the rear enclosure, using that and some darker gray carpet to wrap everything, give it a little bit of contrast.
Wish I had an enclosed garage, I could be working on this while I'm out of work recovering from surgery.
