there is 50.5" between the wheel wells my box is 49" wide and i used some 3/4" scrap pieces to keep it from shifting from side to side. The MLA works great use to drop voltage to 10v before it and now it doesnt drop below 12v. PM me if your needing a T20001 i'll be upgrading soon.

i believe mine is 11 1/2 inches tall. went from as low as i could go in the bed up to the seam below the upper brace. my vent piece opening is 11" and I have 1/4 " MDF on top and bottom with just barely any clearance

I wanna see the 15's

I build my by using 12-15 sq in per cu ft and was told 25" long for 40hz or 30" for 35hz. Maybe someone else will chime in with an exact length. Looking at 165sq in of port

X2 VHT Niteshades, I had to order mine online since it was not offered locally and if you research it there are plenty of how to articles on it.

here it is from the back side

I made it to where the port comes into the cab, as far as changing the size I can always push the back wall out further

that will work I have it on sketch up now but cant figure out how to save it as a pic or I would post it up

I can make adjustments as I haven't built it yet so I can make it a deeper box, just wondering how much longer.

how much longer to be tuned to 30hz?

Perfect, I took a guess on the length. Thanks

anyone wanna tell me what a 8 cu ft box with 121.5 sq in of port 24.25" long would be tuned to. Plan on using 2 -RE SX 15's instead of my P3's now that I blew one of them.

If someone has these I would love to try them. PM plz

so how does it sound? I have a blow through in mine and looking to open it up more so I can get more air moving. I will be changing up the box cuz like Chode mentioned it is tuned way low mine peaks around 28 hz - 32 hz. Just my .02 but I would open up the back wall more.
