you need to wire it in series. look at the second diagram here: http://www.the12volt.com/caraudio/woofer_configurations.asp?Q=1&I=12#results

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

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?

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