Hey, Just because you dont have much room to work with isnt an excuse to skimp on some subs! We offer a custom fit enclosure for your 1998-2001 Dodge Ram extended or crew cab truck. Our dual 10" enclosure is designed to specifically slide directly under the rear bench seat and avoid any passenger leg room loss. The enclosure is a down firing model which both greatly increases the SPL level output and keep the subs of out view to avoid theft. Most entry to mid level subwoofers will drop directly into this box but be sure to check the mounting depth! Our boxes are made from precision cuts of MDF. They are then liquid nailed, nailed and completely sealed. We then wrap them with high quality carpet that matches most vehicle interiors. All Boxes feature high grade spring loaded terminal cup(s) for the absolute best connection possible. All the custom series enclosures are made to fit precisely into your 98-01 Dodge Ram Extended or Crew Cab to the get the max performance from every extra inch of wasted space. We guarantee you will not only see a difference in the quality of the boxes we build, but you will hear the difference and that is what is it is truly all about.
