I just bought a used '06 Durango SLT last week. So far, I love the thing. But, this being my first truck, I still have a lot to learn about it. My first challenge is installing a subwoofer enclosure (2x 12" ported box) in the back. The enclosure is maybe 2" too deep for the third row of seats, so those are folded down. My issue is that the box slides around if I take a turn faster than 15 mph. Any suggestions for securing it...before I get it professionally installed sometime this week?
