does anyone have any bright ideas on their setup of their convertable stereo equipment? I have a 12 inch Alpine V Power sub & V power amp in a custom box in the trunk but I have no room for stuff in my trunk, not like I need to put things in my trunk, however when the top is down the sub is on I cannot hear the bass or feel the bass, any ideas??

by the way its a 1994 Z28 convertable

Also does anyone have a good place to mount an mp3 player in the car?
thanks let me know
Mike
