Thanks for the info. I got a wild hair today to make the trunk lid hydraulic, and controlled from the drivers seat. Then mount 6x9s on the bottom side and facing rearward. With the trunk lid raised to a 40 degree angle, the person boarding could get loud music without sacrificing the view of spotters. Best of all, it is out of sight when you want it to be, and it doesn't take away from the already low headroom of the tower, like the factory speakers. -Kinda stole the idea from the boat that stole our name - 2007 Epic.
