AMP FUSE BLOWS WHEN POWER CONNECTS

I've Got a gasoline e 450 that's blowing the pcm fuse
Chafed cabling is probably the most common cause reason why amps repeatedly blow fuses, and it is almost always the result of sloppy installation. Power cables, or any cable for that matter, should only ever be routed through the firewall with an insulated grommet to prevent damaging the insulation of the cable.

You will see that the fuse has melted, and there might be charring on the panel. A true fuse typically consists of a piece of metal, most commonly an encased wire, that actually melts when overheated.

Car Audio Amplifier Blowing Fuses
If the fuse is blowing as soon as power is applied to the amplifier (with no power applied to the remote turn-on terminal), the amplifier likely has power supply problems. Generally this means that the power supply FETs are shorted or the reverse protection diode is shorted.
What is the reason why my amplifier keep blowing fuses
If they blow, the output stage in either the left or right channel or both are probably blown, with shorted output transistors. These can be removed from the circuit and the device powered on with a new fuse. If the device powers on without blowing fuses, your output stage (at least) is blown and needs to have components replaced.The fuse on an amplifier is there to protect against too much current destroying your amplifier.

Disconnecting shore power = blown 15 amp fuse - Technical
Aug 10, 2015The DC circuit #6 (which is the one blowing) can take up to a 30 AMP fuse as long as you have 10 gauge wire running from the battery to the converter. A lot of manufacturers put in a 15 amp fuse and then this problem occurs. Go ahead and confirm the wire size and replace with a 30A fuse."
Tube Guitar Amp Troubleshooting - Rob Robinette
Most older amps have a mains fuse holder on the control panel or on the back of the amp chassis (usually with a push-and-turn cap). Most Fender guitar amp fuses are MDL "slow blow" or "time delay" 1/4 inch (6mm) wide by 1 1/4 inch (30mm) long.
