The correct size of fuse to use depends on the amp you are wiring. If your amp has an internal fuse, then your inline car amp fuse should be a bit larger. For instance, if your amp has an internal 20 amp fuse, then you should go for a 25 or 30 amp inline fuse. Suppose you have two amps.

How do I calculate which fuse to use?
To calculate a fuse rating, manufacturers work from a simple equation:
- Power (watts) = Voltage x Current (amps) What we really want to know with this equation is the current (amps). …
- Amps = Watts / Voltage. So, let's say we need to work out the fuse rating for a washing machine. …
- 850/120 = 7.08 amps.

What size fuse should I use for my amp?
If your amplifier has an internal fuse, your inline car amp fuse should be a bit larger. For example, use a 25- or 30-amp inline fuse if your amp has an internal 20-amp fuse. If you have two amps with internal fuses, add the amperage ratings together to figure out the right size for your inline fuse.

Can I use a 13 amp fuse instead of a 10 amp?
The 13A fuse in place of a 10A fuse wouldn't directly cause any problem – but then, if there's a problem with the appliance you're using, or if you plug in too many things and the current goes over 10A but under 13A, then under the new fuse the extension lead will keep working whereas the old fuse would have blown.
Do I need an inline fuse for my amp?
Why should I put a fuse before my amp? When running a power wire for your new amp, you should always wire in an inline fuse before the amplifier. If you run this wire without a fuse and your amp has an electrical fault it can cause the power wire to earth against the car body.
