Earlier this summer, my son surfed for one hour straight behind my boat and i had my stereo cranked the whole time. I checked on my amps a couple of
times and the Harpoon was just warm, not hot. My sub amp, the 600.1 was hotter than the Harpoon. The stereo played just fine the whole time - never shut off. Air temp was only in the 70's.
