Well ... I coudn't get my sub mounted under my seat. I had to settle with throwing it in my trunk. Now that its in there it fly around because theres nothing to hold it onto. I used to run dual subs and those boxes would never move. Now that I have a single 10 it flys around the trunk and it scares me. Right now it's sitting in my back seat between the driver seat and the back seat on the floor. I'm pretty short so I move my seat up a good amount when I drive. Any way it's sitting there and actually sounds much better then it did in the trunk but I know it can't stay there. Any ideas on keeping that guy in place?
