I have a JL Stealthbox for the 94-03 Rams. Goes in the center seat section. Armrest still functions. Comes with a JL 12w3-v3 sub. This is THE BEST SOLUTION for rams. You dont sacrafice any useable space in your truck at all. I have heard the MTX enclosure and the JL has approx. the same amount of base with better sound quality. And you dont give up your underseat storage. Asking $300. Approx 3 months old.
