I am not a audio expert but that amp is a 4 channel amp and the audio system on the Harleys are 2 ohm systems so make sure it is compatible.
I would think that a 20 or 25 amp fuse would be sufficient, the main fuse on the bike is only 40 amp and the charging system is 50 amp max.

You should look at the size of the fuse in the back of the amp. Normally about a 40 amp fuse. Then put a 25 amp at the battery on the wire going to the amp. That way if something goes wrong, the 25 amp blows first and you are not taking the fairing off to check a fuse. Ask me how I know this! lol

The fuse at the amp is a 15 amp. I thought that sounded small

There should be a recommended in line fuse size in the manual for the amp.

I have 30amp fuses in all 3 of my amps.

That is very small for the fuse in the amp. I would read up and make sure it is correct.

To protect your system use the smallest amperage fuse that will keep the system operating and in a location you can access easily.
One would think that the manufacture would recommend what will work.
