55 -60 DEGREE CELSIUS,

That seems a bit high, but that amp is class A/B so if it is mounted somewhere with poor air circulation or where it has the sun heating it up those old style amps can get very hot. Best you can do is mount it somewhere where it will have plenty of open air around it. Even the most primitive car amplifiers do have protection circuits which will turn them off if temperature goes higher than the parts can tolerate.

Are you running the components, coaxial, and the sub off this amp? Or just the sub?

My guess is that you are running the components on two channels and the coaxials on the other two channels? And then bridging for the sub? If so, thats why. PWM amps can run trimode but they get extremely hot, QUICK.

Hello Anthony

No actually. My sub is the only speaker connected to the amp, the amp is installed below the passenger front seat, I even have raised to let air blow out over the carpet and added an extra fan, to let cool air in with a rack.
Unfortunately nothing seems helping, now I am considering to buy a new amp as heating isnt something I like

Any recommendations which amp would be good for this configuration. ??

Thanks in advance
