can anyone provide a link or help to where i can find a power supply that would convert 240v to 12v DC providing 10 amps continuous power or more,i need a good adapter so i can power a car stereo up and have sound too. all the adapters i have searched online etc arent good enough any help would be great just locating a decent adapter/converter i,m not planning too use an amplifier or subwoofers just yet i,m more concerned with getting the right converter that can provide enough power for display and sound.
