The type of fuse you use will depend on the current capacity needed and your own preference. For draws of less than 80 amps expect to use a barrel fuse. For currents larger than that you'll probably be looking at the more expensive wafer or MAXI fuses. Fuse Size - Using the method in item two you'll be able to choose the size of the fuse you need. But what if you have a current …

A.) Take each amp, one at a time, and take the amps RMS and (too be safe) divide by 12. (More realistically, your car runs at about 13.8volts, but to be safe, use 12. You could calculate for 12volts and 13.8 and average the two, but we are just looking for a ballpark figure).

First off I would like to thank the contributors of this thread greatly. Second, I had a question about how to calculate the fuse size required for the distribution block. Background: I followed the steps to calculate my total system current draw and my final number is: 171amps. JL Audio 1000.1 = 101amps. Kicker KX600.4 = 70amps.

Then we whip out our calculators and begin doing the math. Number of fuses (X) current rating (X) (12, 13.8 or 14.4 volts.) Then multiply that by .6, .7, .8 or .9 depending on the class of amplifier. There is a major flaw in using this equation. Most fuses have 3 ratings that they must comply to in order to be UL approved.
Calculation of RMS power of an amp by looking at the fuse ...
https://www.diymobileaudio.com/threads/calculation-of-rms-power-of-an-amp-by-looking-at-the-fuse-s.64939/
A quick and dirty way to check the true power output of an amplifier is to take the fuse value of the amplifier (or the sum for multiple fuses) and multiply it by 6 for class A/B amps or 10 for class D amps (higher efficiency). This is by no means an accurate way to judge power but it will tell you if your amp is even close to it's specifications.
