The size can be bigger if the amp already has an internal fuse. The size is also dependent on the placement in the right position. Too small a fuse cannot protect the system even during normal operations. But if you add a big fuse, it can tolerate more power and allow it to go to the system, damaging it.
What kind of Fuse do I need for an amp?
The internal fuses of most amps are mostly some type of automotive fuse. These fuses are of the same type of fuse that is used elsewhere in your car and other audio components. These are flat with two prongs. For instance, the head unit of the car sound system might also use this same fuse.
What happens if you change the size of a fuse?
Altering the original fuse type or size or the circuit breaker size with a larger size will endanger the electrical circuit wiring and components. NEVER UP SIZE A CIRCUIT BREAKER Up-sizing a circuit breaker or fuse will cause the circuit wiring to over heat. Overheated electrical wiring will create a serious fire hazard.
Can I up-size a fuse or circuit breaker?
The answer to the question of up-sizing a fuse or circuit breaker is ABSOLUTELY NOT! Application: Installing an Electrical Circuit. Skill Level: Advanced – a Licensed Electrical Contractor.
What is the purpose of a fuse on a circuit breaker?
The purpose of a fuse or circuit breaker is to protect the electrical circuit wiring and components against overheating and electrical short or fault. Circuit protection with a fuse or breaker is accomplished by specific sizing for the specific circuit and wiring type that is installed.
What happens if you put a bigger amp fuse?
If you use a fuse with the wrong amperage, the fuse won't blow as intended, damaging the circuit and resulting in a much larger repair bill. Rather than risk blowing the circuit, take the car to a repair shop to determine what is causing the fuse to repeatedly blow.
Can I replace a 15 amp fuse with a 20 amp fuse in my car?
The answer: It's possible, but not advisable without an electrician evaluating the situation. You should never just upgrade from a 15-amp breaker to a 20-amp one just because the current one is tripping. Otherwise, you may burn your house down via electrical fire.

Is it OK to use a bigger fuse?
In general, NO. Replacing a fuse with a higher-amp fuse is a very bad idea and can lead to fires. Fuses (and circuit breakers) are rated such that they blow or trip before any part of the circuit gets to a dangerous current.
Is it OK to use higher-amp fuse in my car?
Do not replace a blown fuse with one that has a higher amperage rating. The fuse has a specific amperage rating because it is intended to be the weak link in the circuit to protect the electrical components.
Can you replace a fuse with a bigger one?
CAUTION! Never replace a blown fuse with a higher-amp fuse. Always replace the fuse with one with the specified amp rating. You may install the next-smaller-rated fuse to get you by in a pinch until you can purchase a replacement.
