AGU Fuses
AGU style fuses are very common across car audio and are ideal for small to medium size car audio systems and Harmony Audio offers them in amperage ratings from 30 to 80 amps. Our AGU packages include 5 fuses that feature an attractive nickel plated finish that ensure the maximum current transfer. If you are replacing an existing blown AGU fuse our fuses are universal and will fit into any other manufacturer AGU rated fuse holder.
The purpose of a fuse
In simple terms a car audio fuse is designed to protect your expensive equipment in case of a short circuit somewhere along your power cable. What would be defined as a short circuit could vary but a good example is if your power cable were to become frayed or cut open and come into contact with bare metal it would create a very dangerous situation of not properly fused. At Harmony Audio we like to think of fuses as your insurance plan and we only manufacturer the highest quality fuses using the best materials available.
Harmony Audio offers a wide selection of fuse styles and different amperage ratings and they all come in multi packs so you have a couple spares. So how do you choose the correct amperage fuse? The math is actually pretty simple you take the total wattage of all the amplifier(s) on your power cable and you divide it by the vehicle voltage which in most cases will be 12 volts. So for instance if you have a 1200 watt amp and divide it by 12 volts a fuse rated at 100 amps would be ideal for your application.
