I have a Treo SSX 15'' (specs - http://www.treoonline.com/ssx.html) that is going in a 2004 single cab dodge ram 1500. Previosuly I took out the middle seat and had a ~5 cub.ft box in between driver/passenger seat (looked dumb) If there is room, I want the new box to go behind the back seats. I beleive I have about 1' x 5' to work with, with the seats pushed all the way back, and height doesnt matter too much. I dont know what I want it to be tuned to, I just want it all out loud.
