Inline Fuse value for Amp/subwoofer combo?

[WNC05willys]

ok, I have just received my Rockville ss8p powered subwoofer, I will be mounting it under the center console where the factory sub was. My question is this, what amp fuse do I need to wire inline with the power cable nearest the battery? The directions from rockville show a fuse in the drawing but does not tell me what value to put in there. Any help is appreciated

Manual says 10A.....

It already has a 10A built into the unit, but it's still showing it needs another by the battery, hence my confusion

if 10A is proper at the head, 10A is proper at the battery, its the same value current flow....
The fuse at battery is for short circuit protection

Unless you are running multiple devices off that same power wire, this.

That makes sense, thank you

Unless you are running multiple devices off that same power wire, this⬆.

and if you are you are doing something stupid, wire is sized for a reason. So are fuses....
