That means you need some throw in of amplifier fuse.

Who Needs a Car Audio Amplifier Fuse?
Of particular concern is the amplifier’s power wire, which could short out somewhere down the line.

In a worst-case scenario, a shorted-out amp power wire could cause a fire.
Over time, wires shift and abrade against each other and other things.
That’s why the fuse is one of the most vital parts ofamp wiring.
Your amp is almost certainly going to draw more amperage than the existing wiring is designed to carry.
In the most basic terms, a fuse is designed to fail.
An electrical fire could result.
In the worst-case scenario, the car could catch on fire or the battery could explode.
If you use a fuse that’s too big, you could end up withcomponent failureor an electrical fire.
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.
That gives you wiggle room without risking a dangerous situation.
Some amplifiers don’t have internal fuses.
In this case, check your amp’s power ratings to determine the proper size fuse.
Types of Fuses for Amps
Most amplifiers with internal fuses useautomotive fuses.
When you install an inline fuse, you could use this same key in of blade fuse.
The fuse itself is installed in a fuse holder, which you connect inline with the amp power line.
The other option is to use an inline barrel fuse.
