Like it says...i'm selling my box. This thing is a beast. This is the same box i used to hit 148.6dB on the Termlab w/ only one SX15 and a jbl bp1200.1

41.5" x 17" 20"
external and internal mdf bracing
1/2" threaded rod brace
fiberglass resin on inside
no corners on the inside, resin fixed that
all external edges rounded off

3 interchangable ports each tune the box to a different freq.
-~46.5hz (spl port)
Ports bolt in w/ t-nuts hammered into the inside of the box. Closed-cell weather stripping is on the port baffles to stop any chance of a leak.

This box was in a extended cab silverado and peaked at 49hz w/ the SPL port in. The hole for the sub is cut for and SX15, but could be re-cut for an L5/L7 if needed. The box is wired w/ 12ga speaker wire (blue and silver).

I competed regularly in USACi comps w/ this box. Max i got was 148.6dB, but i saw 148.2dB-148.4db on average.

This box is built like a tank...glued, screwed and counter sunk.

before resin

internal w/ resin

a lil vid w/ the 31hz port in

if anyone is interested, i can put up more pics.

MAKE OFFERS! (no low ballin please, this box has ALOT of work in it!!!)

I'd buy it for my SX but it won't fit in the trunk of my jetta.. I can only fit 32x17x17... could fit a wider box if the damn trunk opening was bigger

do your setas fold down? you may be able to slide it in a door and some how squeeze it through into the trunk. may be a pain in the as, but may be worth it. that box would be very loud in a jetta
