I know some one that had two (2) of them behind the rear seat. Basically, he had the magnets out (to the back of the seats) and the cone facing into the rear cab wall. It sounded great! Thumped like crazy!
He builds boxes with a good price. You use a 6.5 sub, or an 8. I'm heading that way soon. If you get your completed, post pics. I've seen pics of 4-6.5" subs. looks good, but I have no idea of the sound. My buddy has a shop here and he said with the 6.5 and enough power, you'll sound good. :2cents:
I have a couple ideas up my sleeve right now. Gonna figure a way to fit two twelves in the rear. They have these new 12s with a 3 inch mounting depth...Ill keep everyone posted on how it goes. Hopefully ill be done with it soon. Dont think I am going to get to it this week. Gotta help the grandparents move and also figure out a place to store my bike since I keeped it at their house.
