Otherwise, nice box //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

MDF really is terrible for you, not just because of its chemicals, but the fact that it literally is saw DUST once cut.

I remember you saying it stays in your lungs and shit. I need to start wearing a mask

You mean you AREN'T wearing a mask? Jesus man, you're asking for it haha. Ask any painter to go into a booth without a mask, it's that dangerous.

it's a chevy colorado, the old box actually was pretty great after i ported it, it was 49x25x20 11 cubes gross, about 8 cubes after displacement with 5, 6 inch aero's tuned to 30hz.
reason for the burning, is getting a new truck in a month or so, and this box wont anywhere near fit (new truck is a 4door)

first.....assuming it is all single sided...thats 12 cubes gross. If those are external dimensions that is....if that is internal....its a bit over 14 cubes.

Now....saying that it is 8 cubes net. it was for two type r 12's correct? thats ~.2 cubes a piece....so say .4 cubic feet displacement by the subs. that leaves you 11.6 cubes internal volume assuming those are external dimensions. Now....each port at 18 inches long are .1 cubic foot. Seeing as you had....5 ports I believe....thats .5 cubic foot of port displacement.

Now....11.6-.4(subs)-.6(ports)=10.6 cubes net

Im not even gunna mess with ports, because you prolly murdered that also. When designing a box you have to take into account that if you have more than one port you have to divide airspace by however many ports. 8 cubes with 5 ports = one port per 1.6 cubes. That SHOULD be ~16 inches. Your at 18...eating at that 1.6 cubes, and too long for tuning anyways. Theres no telling where your tuned in 11.2 cubes.

Get the ones in the red and black boxes, but NOT the comfort masks. They do nothing. You want the sanding and fiberglass ones (box of twenty costs a bit more than a box of fifty of the comfort masks.).

i'll start wearing the masks too, i was feeling like shit after we got started both days, i thought it was the fast food, maybe it was the dust.
