I spent a little time researching the sub encloses out there for the Dodge ram and could find nothing that worked for me. They all seem to want you to remove the rear folding floors which was not a option for me. I found after using my truck for six months I never use the empty space under the center console so I decided this is a perfect place for a single 12 inch subwoofer. The box was built from MNDF and is 1. 20 cf and air tight. I am running a Audiobahn Q 12 Dual voice coil sub rated at 1000 watts rms. I installed a Soundstream Ref 700 to give it 850 watts. I am very happy with this set up and have more bass than I thought I could ever get out of a single 12. Check out my readers rid for the high end.
