if a fuse blows, do you increase the amps or decrease?

[M@nJo 10+ year member]

their was a website that elaborated more on this, but im not sure if i remember right so ill ask here.

when a fuse (whether it be ANL/AGU/MAXI/MIDI) blows, do you increase or decrease the amperage of the fuse as your replacement?

does the same answer apply to the fuses used for car stereo or just in general? (IE: #3 of the "big-3", fuse by battery, etc)

It depends on why the fuse blew. Normally you dont change it at all. Fuses normally blow because of shorts in the circuit, not because your amplifiers are drawing too much current under normal operation--- if this is the case, you should increase the fuse size, but never to exceed the maximum amperage draw your power wire can handle... (which you should have that size fuse in there to begin with)... there are charts all over the net about what size fuse to match with different lengths and guages of power wire. Consult those.
