Moscow Nell - I had the same problem and got an adaptor from Halfords for about £5.

Here's a few things that come to mind. An auto charging system will operate normally from about 11 Volts to about 14.5 Volts, depending on what is operating (lights, blower,etc), and whether the vehicle is at idle or not. Most car amps will operate from about 10.5 to 16.5 Volts, and outside that range, they will probably shut down.
Another consideration is your 20 volt power supply. You didn't mention if it is a DC power supply, but it needs to be. The other factor is its output, meaning its amperage rating. I'm figuring it will need to put about 5 amps, at the least, for the Sony to put out some watts. I think the line fuses of the Sony are rated @ 25 amps each.
I don't like this type of situation, because I want to say 'try it and see what happens" and I want to say 'don't do it, something may blow".
If you decide to try the 20Volt power supply, maybe if you put smaller rated fuses (say 10 amp) in the Sony amp, they will act as a fail safe. Good luck!

sounds like it's getting really hot, that round thing your talking about is kind of a step up transformer which causes inductance and will increase the voltage that the other components need to run properly. It's copper wires wrapped around a piece of iron like an electromagnet. So what is you question?
