Hey guys, I'm pretty new to the car audio world, being that I'm only 16. But I have worked all summer and have finally saved up enough for my first system. I want to get a 12" Q and I want to build my own box but I want to get it all planned out before I start ordering everything. I have designed up a ported box that is 25"x20.25"x14.625" and is tuned to 32 Hz and has a net internal volume of 2.2 cubic feet. My question is how much bracing do I need to use and I know that it will reduce the volume, but what will that do to the frequency of the box?

You souldet need much bracing. you wouldent realy need any bracing as long as the box is made of at least 3/4 mdf. And if I where you I would have a double layer front baffle just to be safe

Ok cool that makes it easier. I had already planned on doing a double layer front baffle. Thanks a lot.

do you have room to make your box bigger?

I do, but I would rather keep most of my trunk space.
