Fan are the best idea ive seen in this thread. Worked for me. Summertime was average 110 or so. Car was black and amp was located about 3-5 inchs from my trunk lid. Needless to say it was a frickin oven in my trunk. 4 small fan mounted on my trunk lid firing onto the amp stopped my amp from over heating so fast. From 10-15mins to a couple of hours of consistent heavy use. Yes fans do work.
