I was having some Friday fun listening to music fairly loud for an hour and a half or so. When I was done I took the opportunity to measure the temperature of the heatsinks on the sides of my amps. One measured 130F, which was considerably more than the others.
I have one P2200 and 3 P2201 amps (same except the P2200 has meters). I run the 4 amps bridged, giving each of my JBL L150 and L100T speakers their own amp. After that hour and a half of music, the left and right heatsinks of each amp all measured in the 95F-100F range, except for that one side that measured 130F, and the one right above it that measured 110F, probably just due to the heat rising from below. Ambient temp was 74F.
Considering that I was pushing them hard and the halved impedance of the load due to the amps being bridged, I expected them to be hot, but having one out of the eight sides running so much hotter would seem to indicate a problem. Any ideas?
