[QUOTE="Joebobclark, post: 8515867, member: 574696"] Sounds about right... Mine is 38" wide, 30.5" high and 29" deep external dimensions... It was supposed to be 32" high, but I couldn't fit it at 29" deep and have the front be where I wanted it. Im 6ft, and like to drive relaxed, so I set the wall back further to allow my seat where I want it since this is my daily driver. Mine wont slide in/out because of the height, built it in the truck. It's doubled walled all around and double baffled, so internal after displacements leaves me right at 4 cu sealed and 11.5 cu ported. Easily could have gotten more airspace by building out over the wheel wells, or moving the front forward for more depth, just didn't really need it for my 2 15's. If you are going single walls with just bracing, should be able to get 5 sealed/13ish ported, I started with a bit over 20 cuft as well. I will tell you I wish I had given these 15's a little more on the sealed side. Having no TSPs for them, except what I could pull from them with my DATS, I went a bit conservative. I think I would have gotten more lows with a little larger sealed section, FS I pulled from the subs are around 32hz, but I also am not planning to run a ton of power to them. If you are going to be giving the Evils rated or higher power, better to keep the sealed side smaller for control. I built my ports at 200 sqin (20x10), tuned to 46-47 on the daily, and 53-54 for SPL. I haven't really played around with it yet, but I figured that would be my maximum port area and I could shrink it down if need. Metered the daily port, it was peaking at 36hz, did a 144.7 with a very conservative "by ear tune". Will have it back together tomorrow, and get it tuned with my o-scope. Hopefully, play around with it Saturday and see where my peaks are for both ports and get a meter on it at full power.... [/QUOTE]
