Well, it took my lazy butt long enough , but Iíve finally started some real work on my Rear Center Enclosure (RCE) project for my 05í double-cab.
All pics are in my RCE gallery, but Iím going to post a few here, too.
Of course, all of us double-cab owners know just how hard it is to add bass to these trucks.
First, there's VERY little room behind the back wall of the cab. I just barely squeezed my amps back there (see audio gallery). Unless I wanted to take the time to glass the whole back cab (and even then I figure you can only fit a few shallow-depth 8"s back there), there wasn't a behind-the-seat solution to adding some bass.
Second, I could have just built a spec box and thrown it in the back seat, but that just gets in the way of passenger seating. The reason I bought this truck was to tote more folks, at least two rear passengers, so I'm not willing to give up that space to a big-ol' box.
Now, there are a few off-the-shelf options, like the factory-purchased drop-in enclosure ($$$$ ) or the Bazooka drop-in, that allow a pair of 8's or 6"s (SAS) to fit in the storage space under the rear seats, but that just wouldn't provide me with enough low-end for my tastes.
So, necessity being the mother of invention, I talked to ma' and decided to venture on my own. Granted, my project isn't going to set any SPL or design records, but it's an option, nonetheless.
I wanted some extra thump, without giving up too much space in the rear. What I came up with is a center console, to house one eD 11O.v2, that sits on top of the seat, is held in lateral position by integrating the factory rear arm rest, and wraps (curves) down to the floor. Nice thing is, when I need to remove the enclosure, I simply disconnect the box, raise the arm rest and slide the whole thing out from either side.
I had originally wanted the sub to be down-firing, but I played with my temporary enclosure in that configuration and it seemed to lose all low end, becoming to "punchy" and tinny-sounding . So, I opted for the front-firing set-up.
I've finished the basic construction and spent some time this weekend fiber-glassing the front and rear open portions of the box. I've never glassed before, so please pardon any obvious flaws. Those will be concealed when I have the enclosure covered.
Here are the sides of the box, just mocked up and test fitted into the back seat:
Here's the completed basic construction, ready for fiber glass:
Here's the first layer of glass, on the interior of the top-portion of the RCE. I only plan to add more glass to the interior, and maybe just two more layers. Is that too much?
This last one is of the top of the top-portion, with one layer of glass. I don't plan on building up the top any more with glass. I'll fill and smooth it with Bondo, next.
After the glassing and sanding, I plan to test the box out for a week or so to see if I'm happy with the sound. If I am, then it's off to the upholstery shop for some leather-texture covering (to match the factory center console material). If I'm not happy, well...........I've always preferred the sound of a 12" sub over 10"s, so I might adapt the design to a shallow-mount 12".
I only managed to get the first couple of layers of glass down on the top portion of the RCE this weekend. Iíll continue working on it over the next couple of weeks and will post more pics, as time allows .
Just wanted to share. Thanks for the space.
