If you do fit them behind the trim panels I personally would add some cooling. Bilge pump blower fans are the most efficient but very loud, if you want minimal noise I would use PC fans, equal intake and exhaust. You could make a grill over these with some grill cloth if you're going for a stealth install, and this would also prevent large particles from getting back there, much like a filter on a PC.
