How to select the proper fuse size for car audio?
Class D amps are about 80% efficient, so take your figure from your class D amp, 125amps, and multiply it by .2 (or 20%) to add efficiency. 125amps (from the total RMS/12 of the class D amp) + 25amps (the class D efficiency) which gives you 150amps. So your 1500watt class D amp will draw around 150amps.
Do you know the point of a fuse?
The point of a fuse is to have the fuse open before this wire burns. 2.)
