New box for my DC

[Hell-Razor 0]

Im BACK! After being gone for a while traveling the world I have come back to my fellow members / friends / people / dudes / dudettes and folks on the good 'ol ssa forums (good job Mark). I am starting a rebuild once again. I literally blew my old box apart so its time to go bigger, badder and more bracing! I noticed a huge improvement from my 3.5cuFt box to my 4.25cuFt box. I hope to do the same when I hit a 4.75 ish box. I am installing into this box a single DC 15" woofer being powered by a 3500D.

Here is what my plan is:

BOX:

Height: 17.5in

Width: 38in

Depth: 18.5

CuFt: 5.083

Square Port Volume Internal: 1134

Square Port Volume Displacement: 1144.125

Tuning Frequency: 33.5hz

I also plan on buying a sound deadening kit through second skin audio to stop my trunk from freaking out (and hopefully get good meters this year).

One question I had is about bracing. Is it possible to not do any internal but all external? I know the width will need it (the height should be ok I think) so could I do this - make it so the top and bottom sandwich the back (screw in from the top and bottom) and sides get overlapped by the back plate (so the sides are screwed in from the back) and then place a bigger piece and overlaps everything and re crew that in from the back. Then secure it to the back of the box (it overlaps the top, sides and bottom) using glue and dozen screws or so? In theory it makes the .75 turn into a 1.5 inch thick back plate.... if that makes sense then would that still need bracing? I know bracing does not take up that much room internally but if this way works as well then why not, seems easy.
