Where to place my 12 subs?

I know you already have your subs but if you really want to save some space you could try the new pioneer shallow mound subs. The mounting depth is only about 4 inches for a 12. The manufacture recomends a .5 to 1.0 cubic ft box. You could tuck 2 or even 3 of these up against the back of your seat and not take up that much cargo space. Check them out at www.pioneerelectronics.com. The model number TS-SW3041D

I will take a look at the subs. I was thinking about making my own enclosure out of fiber glass. I never did it before but I think I can learn. Any inputs? I was reading this guide and I may just do it. http://chris.pfharlock.com/glass/index.htm

Fiberglass is a good idea.  Take a look at this guide too.Support the12volt.com

That guide was truly the thing that made me really want to do my own project. It was almost the same thing I had in mind but with 2 of my subs. I truly appreciate the help and I will keep you updated. I will start buying the materials little by little. I had nothing in my truck before I bought it and little by little I have been adding more things. I have a flip down 12 inch lcd tv, a xbox, and now I look forward to this project. Thanks DYohn for the input on the guide.

fiberglass is your best bet for something trick,there are alot of pre-fab boxes out there that are great and would suffice for a quick install, but if you want the looks and the feel of something custom....DIYrtfm

What's the whole list of materials that I need to do my own fiber glass enclosure? I get paid today and I may go and buy some materials.
