"running hot" or "too hot" is a topic that comes up on the forum a lot and most often, there is never any actual temperature reading to support the "too hot" concern.
It's always difficult to determine what "running hot" really is and most often people put there hand on the amp and say it's "too hot to keep their hand on the amp for more then a few seconds".
Putting your hand on the amp is no way to determine how hot the amp is getting and in no way can determine how hot it is or wether or not it is too hot.
Example: Put your hand on your dashboard around noon after it has been exposed to the sun for a couple hours and you won't last more then a couple seconds and yet all of the electronics in your dash board works just fine.
How hot does your dash board get?..... maybe 120-130 degrees?
Some say 100 degrees is too hot but the water in a hot tub is 100-105 degrees and certainly no concern to you and definately not electronic components.
Almost all amplifiers have thermal protection and certainly all of our amplifiers have this feature built in.
Our amps have a thermistor on the heat sink as close as possible to the output devices which are creating the heat.
The amps are designed to shut off if the heat sink should reach 165 degrees which is as hot as you would want the amp to get before component failure.
Now, having said this, it doesn't mean that your amp is not running hotter then it should and there are many things that can cause an amp to run hotter then normal....many have mentioned some of the cases.
rather then trying to guess or go back and forth here with 20 Q & A, I suggest calling our tech support line 877-629-9227 and talking to the tech.
He would be able to properly trouble shoot the problem (if there is one) and help you resolve it.
