What size fuse do I need for a 1200 watt amp?
You should use at least a 100A fuse.
How many watts can a 25 amp fuse handle?
Circuit Capacity Using this simple relationship principle, you can calculate the available wattage of any given circuit size: 15-amp 120-volt circuit: 15 amps x 120 volts = 1,800 watts. 20-amp 120-volt circuit: 20 amps x 120-volts = 2,400 watts. 25-amp 120-volt circuit: 25 amps x 120 volts = 3,000 watts.
Why are there fuses in most audio products?
Most audio electronics contain at least one of these to protect the component from short circuits, surges, and other electronic ailments. The problem from an audiophile’s perspective is the low-quality materials that are used to make commercial versions.
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.
What to do when your car stereo fuse blows?
When your stereo fuse gets blown, you need to start with something simple and obvious. You need to first check the amperage rating of the circuit for your car stereo. In this case, you could also go through the manual of the vehicle that contains the complete information regarding the amperage rating with a proper diagram.
Do you know the point of a fuse?
The point of a fuse is to have the fuse open before this wire burns. 2.) Next, you have to understand the point of the fuse as explained earlier, so obviously you want to make sure the fuse is not larger than the max. capacity of the wire, as we want the fuse to open (or blow/break are other terms) before the wire burns.
