A question to the stereo/electronics gurus out there...
I'm putting together a little boombox with a 20w rms x 4 headunit powering a pair of 6x9s for home use.
I was wondering what the power requirement for this sorta setup would be.
I have an old 12vdc power supply rated at 5 amps and 50 watts that can't supply enough power to the head unit to play at moderate volumes. Then I realised it's running a 1amp fuse that wouldn't blow! Does this mean this power supply's putting out less than a single amp?
Also, can someone explain the difference between a regulated and otherwise ac to dc power supply?
Any advise would be appreciated...
