I was at a local car audio shop here in Harrisburg, PA. And I heard this boomin even before I walked in!! As I walked in I was expecting 2 12's or something big to be bumpin like that. OH MY GOSH!!! It was just one of these subs (premier ts-sw124d) in a real thin box. I was just wondering if there any way I get this sub behind the backseat? ? ? All I would need is one! I have a 2000 nissan frontier crew cab. You guys gotta here this thing!!! I also have a contour that has 2 12's and this one sub sounded better than my 2 12's.
