EDIT: I don't Understand 10AMPS Power Supply...

EDIT: How many AMPS do i need to run this amplifier?

10Amps * 13.8Volts = 138Watts
No it's not enough to support a 1000 watts audio system.

Huh? Why on earth would you want to use a bench top power supply to power your car audio, assuming you could do it in the first place.. considering it needs to be plugged into the wall?

😕

10A * 13.8v = 138w output


Now, assuming your stereo *actually* puts out 1000w, even with 100% efficency, its going to draw 72 amps @ 13.8v

lets say its running at 75% efficency. (eg. 1250W consumed for 1000W output)

that would mean you need ~100A to power the sh!t.



lucky for you, most stereo manufacturers lie through their teeth (for ex, how many "1000W" amps do you see, with 12ga wire coming out (to V+)? no way that 12Ga can handle the actual 100A+ req'd

of course there are legitimate amps that can actually put out 1000W RMS or whatever, but its not going to be free...

You could probably use that 10A power supply you asked about before. But you won't be able to turn up the volume to max.
If you want to have a powersupply that can handle the amplifier at full load, you would need about 40A output.
(class D amplifiers usually run at about 85% efficency)
But why do you want to run it of a powersupply?
