i have a 10" subwoofer in a custom enclosure along with an amp hooked to my shaker 500 mounted on the hump in my trunk. this whole wet up probably weighs in around 40lbs or so. i would like to mount a board behind the rear seats and mount both the amp and just the subwoofer (no enclosure) on this board so it can be easily removed when i'm going to the races. does the subwoofer actually need to be in an enclosure, or will it still work (and sound good) if mounted to what us old guys would call a baffle board? of course i could fire the woofer either toward the trunk or the rear seats.... let me know, kthanks.
