Internal damage to Mirage BPSS-210 Subwoofer amp
Something getting hot probably means something shorted out.
You probably know that since you replaced the fuses already...
.
Can you give me some idea of what you do and do not know about electronics? Then I will say fewer dumb things.
.
When troubleshooting any electronic device, especially amps, open it up and look at the circuit board. Look for burned board and components. Then test to see if the burned/blown component had reason to blow (it probably did).
.
Often a shorted transistor runs too much current through some other component and the other component blows up.
.
Another cause, less common, is a shorted cap.
.
Look at the schematics if you have them, if not, you may have to create one to make sense of it.
.
Or take it to a shop where somebody does this all the time. The only one here went belly up in the last 12 months...

About the pots
.
Try blowing out the pots which are popping with some tuner cleaner. Use with caution, and always with everything turned off and power cords unplugged.
.
Pots do not usually make popping noises unless they are very old or live in a very dusty place...
.
I found the manual, but no schematics...

You might be able to get better, more exacting help on the Mirage Forum...

But maybe not, since the Subwoofer section gets less than one post per month, and the much busier Technical Questions section only has 23 in the last 12 months.
