Car amp internal power supply question
How can I determine if the internal PS in a car amp can take a range of voltages?
If you look at this amp for example:

the spec says:

power supply is on board, you will need only a suitable external transformer with 18V AC secondary winding, 160W or more. You can even power it with a DC power supply, 12 to 27V DC, if you have a good one.

I have an Avionixx Tripath car amp that tends to run hot with a 12.7 V DC, 150W power supply. I was wondering if higher supply voltage would possibly make it work more efficiently - ie cooler.
Can I tell from looking at the parts on the circuit board if the PS in the Avionixx is of similar design as in the Audiodigit amp?
Here is a pic of the insides of my amp.

BTW, I did ask Avionixx directly by email but haven't gotten an answer.
