Specs for a 12" sub box

For the wheel-well or the drivers side enclosure ... does anyone know the specs to build a box for a 12" sub? It will fit, right?

Re: Specs for a 12" sub box

Mine is custom made from a guy on ls1.com ( BJ was his name ). 12" drivers side fibergalss box. I think it is around 1.3^3ft of airspace.

I can take some measurements of it if you like, just email me.

Chris <hr /></blockquote>It's a 12" MTX sub... but I assume you mean the box <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

It's custom... meaning there probably isn't a straight edge on the entire thing. I made the front and bottom out of some 3/4" MDL (whatever that particle board stuff is called) and the rest out of fiberglass. Fiberglass is not hard to work with and is easy to grind down and re-lay if something doesn't fit quite right. And it doesn't matter if it is ugly or amorphous when it is behind/under the panel... the front is carpeted.

So you used particle board and fibreglass? How's it sound?

Chris [/QB]<hr /></blockquote>Go to Home Depot and get a can of the resin and hardener... works just like bondo <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> Get some fiberglass mat... the finer the weave the better. Basically, the resin is what hardens, but the fiberglass sheet is what basically holds the resin in place until it dries. The amount of (clear) hardener added affects the speed at which the resin dries.

BTW, it sounds great. Thick enough fiberglass makes a pretty sturdy box, which is basically what they make the Stealth box out of too I think. I am 100% happy with it. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

A dermmel tool with a sanding bit will allow you to fix a lot of places which don't fit 100%... try not to breath the dust <img border="0" title="" alt="[Frown]" src="gr_sad.gif" /> Like I said, it doesn't matter what it looks like behind the panel or under the front carpet. Feel free to grind, fit, and re-lay the glass a few times until you get it right. It IS that easy... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

EDIT: I tend to pour the resin into a tupperware bowl... cut the fiberglass mat strips into appropriate sizes/strips... add the catalist (clear liquid)... dip the strips in the fiberglass and lay them on the box in the appropriate places. When I am out of strips of glass mat, I pour the remainder of the resin/hardener on the box to harden...
