When your amp keeps blowing fuses, the amp will simply turn off after a few seconds and you may notice strange burnt sent. There can be various reasons why an amp blows fuses. In some cases, it might be a simple issue that can be easily fixed. However, there might also be a more serious problem that requires professional assistance.
The main reasons your amp keeps blowing fuses are a short circuit, faulty wiring, a loose connection, excessive heat, or damage to the power supply or output section or the amplifier.
Below is a quick explanation of each issue.
Reasons Your Amplifier Keeps Blowing Fuses
1. Short Circuit
In most cases, an amp blowing fuses is due to a short circuit. This can be caused by a variety of factors, such as faulty wiring or a loose connection. If you suspect that your amp has a short circuit, it’s best to have it checked out by a professional.
2. Excessive Heat
Another common reason for an amp blowing fuses is excessive heat. This can typically be caused by improper ventilation or overloading the amp with too much power. If your amp constantly blowing fuses, make sure to check the ventilation and cooling system.
3. Damaged Power Supply
If your amplifier’s fuse blows immediately when you turn on the amplifier, or immediately when the fuse is inserted into the holder, the issue is normally a damaged power supply or output section. In this case, the amplifier will require servicing.
4. Faulty Wiring
In many cases, faulty wiring can cause your fuse to continuously blow. To check if the issue is the power wire, simply disconnect the amplifier from the power wire. Next, you need to use electrical tape to insulate the amplifier end of the wire from grounding against the body of the car.
Next, attach another fuse and see if it blows. If it does blow, then there is likely a break in the wire (or the insulation jacket) where the raw wire is touching the metal of the car. You will need to find this and fix it. You will need to trace the power wire from the engine compartment into the car’s interior. Normally, breaks can happen where there are moving parts like at the door or at sharp edges.
How to Fix an Amp That Keeps Blowing Fuses?
Step 1: Remove Power from the Amplifier
Before working on any electronic device, including an amplifier, unplug the power cord and turn off all internal switches.
Unplugging any device will remove power from the unit, but if it has an internal switch, you must turn it off as well. Turn on a circuit breaker or pull all fuses until you see that there is no electricity running through the amplifier before removing the cover of the amplifier.
Step 2: Remove Cover
Locate screws on either side of your amplifier’s case and remove them with a Phillips screwdriver.
Pull up on the top of your amp to release it from its place and then lay down somewhere that you can work on it comfortably.
Step 3: Find the Blown Fuse
Some amplifiers use glass tube-type fuse holders while others use blade-type fuse clips. In either case, the blown fuse will have a black spot in it or will be completely dark. Remove all fuses for replacement.
Step 4: Determine the Type of Fuse to Replace It with
If you are not sure which type of fuse your amplifier uses, look on the inside of the amp to find a model number or manufacturer name.
Look up this information online or call an authorized service center for your particular brand and model.
How to Fix an Amp that Keeps Blowing Fuses at High Volume?
If your amp starts blowing fuses at high volumes, there are a few steps you can take to try to fix the problem. For some amps, instead of blowing the fuse, they will go into protect mode at high volume if there is an issue.
Step 1: Ensure that your amp is not over-heating
If it is, try to give it some more ventilation by moving it to a cooler location or installing a fan nearby.
You can also try lowering the wattage of your amp until the fuses stop blowing. If neither of those solutions works, you may need to buy a new amplifier.
Step 2: Don’t keep trying to use an amp that keeps blowing fuses
This could damage the amp beyond repair and cost you even more money in the long run. Instead, take your amp to a technician who can diagnose the problem.
If you don’t have a technician in mind, contact a company like Audio Innovations for more information and assistance.
Step 3: Lower the wattage of the amp or change the resistance of the speakers
When your amp blows fuses at high volumes, it means that your amplifier is not powerful enough for its current configuration.
This can be solved by either lowering the wattage of the amp or changing the resistance of the speakers to match what is being put out from your amp.
In many cases, however, an amp that keeps blowing fuses simply needs to be replaced with a new one that matches what you are trying to do.
What Are Amp Blown Fuse Symptoms
If you are experiencing any of the following symptoms, it may be indicative that you have an amp blown fuse:
-The sound system in your car is not working
-Your car’s headlights are not turning on
-Your car’s taillights are not turning on
-Your car’s dashboard lights are not turning on
-Your car is not starting
If you are experiencing any of these symptoms, it is important to take your car to a mechanic as soon as possible to have the issue diagnosed and repaired. Ignoring the problem could potentially lead to further damage and more expensive repairs.

How to Fix 2-Amp Fuse That Keeps Blowing
There are a few simple steps that you can take to try and fix a 2-amp fuse that keeps blowing.
Step 1: Ensure that there is not too much power drawn on the circuit
You can do this by checking the wattage of all the devices that are plugged into the circuit. If there is more than a total of 1000 watts on the circuit, then you need to remove some devices until the total wattage is below 1000.
Step 2: Check the wiring on the circuit
Make sure that all of the wires are properly connected and that there are no loose wires. If there are any loose wires, then you need to fix them before continuing with the rest of these steps.
Step 3: Ensure that your ground is working correctly
To do this, take a voltage tester and check for 240 volts between the hot wire and the metal to which it is grounded. If there aren’t 240 volts present, then you need to call an electrician so they can fix it for you.
Step 4: Replace the blown fuse
The final step in trying to fix a 2-amp fuse that keeps blowing is to replace the blown fuse with another one and turn on all devices at once while watching the fuse.
If the fuse blows again, then you know that there is something else wrong with the circuit and you need to call an electrician.
Why Does My 30-Amp Fuse Keep Blowing
There are a few reasons why your 30-amp fuse might be blowing:
- You may have too many appliances plugged in at once.
- You may have a faulty appliance.
If you’re not sure what’s causing your fuse to blow, it’s best to consult with an electrician. They can help you identify the cause and help you fix the problem. In the meantime, it’s a good idea to unplug any unnecessary appliances until you get the issue fixed.
Failing to do so could result in a fire hazard. So, if your 30-amp fuse is blowing, take some time to figure out why and take corrective action. It could save you from a dangerous situation down the road.
Why Solid-State Amp Blowing Fuses
A solid-state amplifier blowing fuses is not a common occurrence, but it can happen. When it does, it’s often due to a defective component or an improper installation.
In some cases, the fuse may simply be too small for the amp. If the fuse isn’t able to handle the current draw of the amp, it will blow. This can be caused by a short circuit or by too much power being drawn from the amp.
If you’re having problems with your solid-state amp blowing fuses, have a qualified technician take a look at it. There may be something wrong with the amp that needs to be fixed. Otherwise, you risk damaging the amp and/or causing a fire.
Blown Amp Symptoms
There are many possible causes of blown amps, but only a few common symptoms. Here’s what to watch for.
1). No sound
If you power up your amp and it seems okay, but there is no sound, most likely the problem is either with the speakers or (more commonly) with the preamp tube sockets.
For example, regular 6V6s will make noise when they are missing one cathode resistor; this may cause strange hums or oscillations at high volumes. Bad speaker connections can also kill output. Also, check fuses first before assuming that the tubes are bad.
2). Erratic behavior/crackling/popping
This can be caused by several things, including bad tubes, dirty or corroded sockets, loose wiring, or bad capacitors.
3). Low volume
A blown amp may still put out some sound but at much lower volumes than before. This may be due to issues with the power supply, speaker impedances, or other factors.
One of the most common signs that something is wrong with an amp is an increase in heat. If your amp is running hot even when you’re not playing it hard, there’s probably a problem.
This is an unambiguous sign that something has gone seriously wrong. If you see any smoke coming from your amp, turn it off and unplug it immediately.
