Why does the fuse from the amp always blow out???

Question

what could it be???

it works for a little and then blows.

the longest it lasted was 10 minutes the shortest was maybe 2 minutes.

Answer 1

Sounds like your fuse is undersized.  You *might* have a short somewhere.  

What size amp?  How many speakers?  Are you running a cap?  What size wires?  All of these are required to better determine what exactly is causing it.

Answer 2

either you have the wrong fuse, the amp is fried, or too much power going into it.

Answer 3

match the fuse amperage with the on in the amplifier.
