Finished MDF box to JL specs for 12w6v1

Built it out of 3/4" MDF.....24" wide x 14" high x 16" deep, with slot port. Damn the thing is heavy. 2 cubic feet too!

Probably cost me about $35-40 in parts to make it....pretty cheap considering.

Sound is hella louder in low bass.....now I think I need to upgrade to a better quality amp from the POS profile california I have.

only real motored toys left:
'06 GSX-R 1000
'07 Mazdaspeed3- injen CAI.

I'm not sure what it's tuned to. whatever the box is on the manual, the ported one it's 2 cubic feet after displacement I believe.

as long as it's solid and there are no leaks
the important thing is, does it sound good?

btw - my box is pretty ugly too, don't worry about it

it sounds hella better. I thing the problem now is the lack of tight parts back there (lotsa rattles) and a crappy amp.

Yeah, it took a LOT of deadening to clear up the rattles in my car, and I still haven't killed them all. I have a small rattle in each door near the mirror, my rear view mirror, sunglass holder, and the rear passenger side "oh shit" handle are my only rattles now. Still annoying though. If you deaden the trunk lid and the rear deck I'm sure you'll find most of the rattles will disappear.

Are those internal or external measurements?

Looks like 3.1 cubic feet to me.....

14 x 24 x 16 / 1728 = 3.1

port displacement takes up a LOT of room

Going by external measurements my box appears to be a 2.2cf, but it's actually 1.5 with a 56" port inside.

This is true. His post says a slot so I am assuming it is made of MDF and simply changes the wall of one side into a port....

Are you using a tubular port?

low tuning with a lot of port area takes a looooooong port, kinda sucks that the box is so big, but it's worth it
