A friend of mine runs a company called Subsolutions,
http://subsolutions.com/ And they build amazingly small boxes, that will blow your mind when you hear them. I have run one in my Stang for a couple of years, and I love it, but when I got the Titan, I was less than happy with the stock stereo, and this prompted a trip to the Subsolutions factory. They make a Frontier box that is really popular, so i figured they'd have something for me. I ended up getting an F-150 box, and it fits either under the seat, or like mine, behind the seat. I have an amp with a line convertor hooked to the stock radio, and it sounds really nice. Any AZ Titan owners are welcome to come hear it. The price was $249.95 with the speaker. So thought I'd let you guys know there's something else out there for us, that takes up almost zero space.
