What should I do if my amplifier fuse blows?
What should I do if my amplifier fuse blows?
If you cannot see all of the wire, disconnect it from the amp and see if the fuse blows when it’s inserted into the fuse holder. If it does not blow, the wire is fine and there’s probably something wrong with the amplifier. With more experience, you’ll be able to test for a short with an ohm meter.
What causes a 12 volt fuse to keep blowing?
If your 12 volt accessory port fuse keeps blowing, check for a faulty accessory power plug. Faulty phone chargers cause a ton of issues. 1 Fuse Amp Rating Too Small A fuses purpose in this world is to protect your car’s wiring, so in a way we should be happy it blows, but I never am.
What should the current be when replacing fuses?
When replacing the fuses, temporarily install fuses rated at ~1/2 the current of the originals. This will help protect the amp’s power supply and circuit board if they were not damaged when the amp blew the original fuses.
Why does my DBlock amplifier keep blowing fuses?
If the main fuse isn’t blowing but one of the fuses in the dblock is blowing, that tells you that there is a problem beyond the distribution block. It could be that the wire feeding the amplifier is shorted to ground or there is something wrong with the amplifier. If you can see the entire length of the wire, make sure the insulation is intact.
Why does the fuse keep blowing on my subwoofer?
The fuse blows because there’s a fault in the amp. It’s probably cheaper to replace the amp than fix it, assuming the driver is OK. Click to expand…

Why does my amp keep popping the fuse?
If the power wire is too small in diameter or damaged, it could cause an abundance of resistance, which creates heat, which in turn makes the amp work harder. The extra heat from the resistance could cause the amplifier’s internal safety to kick on, popping the fuse. Inspect the power wire to the amp,…
