I have a huge ported box that takes up most of the rear cargo area real estate. With a speaker box behind the front seats, a CD changer attached to it, and a 10" sub box, my stereo takes up altogether too much space. When I feel really ambitious I might put the 6 1/2" speakers somewhere out of the way, move the CD changer, and make a smaller subwoofer enclosure. But it sounds great for the money I put into it!
