## Re: are the fuse ratings on an amp how many amps it draws?

By using an amprobe. Clamp it on and it will tell you how many amps you are pulling. Or you could do Watts x Volts = Amps, but it will be a little higher than that based on how efficient your amp is.

Custom box 4.0 cubes at 32 HZ

MB Quart RAA2400 800 Watts

Polk Audio 3 ways in rear and doors

A good start is by determining current draw based on power output and efficiency.
