too late, design finished, lol We already talked earlier so ur decision should be final or around that by now. Here is your design- This is what it looks like for competition use- Box external - 37" wide 25" deep 17.5" high Box Internal without port displacement- 35.5" wide 22.75" deeo 16" high Double baffle used! Port build internal dimensions- 16" high 8" wide Internal box specs- The angle piece is placed as follows- Measuring from the back left corner on the INSIDE- From the back, measuring to the baffle, go down 10" (outer mdf layer, 9.25" inner layer) From the back, measuring to the right, go 21.75"(outer mdf layer, 21" inner layer) you may only need to brace some walls with brackets or small runs of wood, no wall-2-wall bracing required. Box tuning specs- 16x8" = 128sqin of port tuned to 46.5Hz Competition use port. Here is your daily design- This piece will slide into the port to adjust port tuning. This piece is- 16" high x 4" wide x 20.25" deep. This will allow 4" of width throughout the port now. The port will now be - 64sqin of port tuned to roughly 33.5Hz What you will want to do is build this plug and modify the internal port volume so the plug can only go back 20.25" deep. How do you do that? there are many ways really... You can glue very small pieces of wood just tall enough to stop the piece from sliding back any further once it hits the piece and another on the side so it stays uniform while you slide it back. Remember, when building the plug, even though i said what the size of he plug is, make it about 1\8" smaller on the height. You do not want it perfect because it will be almost impossible to slide in and out. Trust me, i've seen it happen before. It's ok if you have a little "wiggle" room, just nothing too bad. I wouldn't go any smaller than 1\4" though... so you can make the plug as small as 15.75" high x 4" wide x 20.25" deep. I would build the plug, slide it in, then trace around the plug and choose where u want to place these little barrier stops at... Try not to make them large... 0.25" tall is plenty and just a 2-4 inches long is plenty. Don't fill the port with barriers all the way around the plug either. Just put one in the back and one on the side and that's it.

Alright and when your measuring the internal volume you take the width*height*depth and subtract the total volume of the port right? So if I have a box 14*14*22 for internal dimensions and a port 2.5in wide, and 14in tall, and 26in long(35hz), I would do the volume calculation and subtract the port volume from overall box volume correct?

Here it is hooked up and installed.... And here is a video, most of the flexing didnt show on video, but this thing is brutal. I have dash movement, some plastic/rubber pieces came out from somewhere by my sunroof, the sunroof slaps like a S.O.B, my windows don't go up or down anymore for some reason??? I think bass rattled a connector loose on the switch. Also, I ordered a set of DD audio 6.5 components for the front. They should be here by Tuesday in time for the competition coming up the 16th.

Not so sure, you've been given some seriously crap advice but with the way you react it isn't a surprise.
