If I had a fuse that supported a 750wattrms amp in the fuse box instead of using the one that the amp gave me, would that cause any problems? The reason I ask is becuase the two that they gave me keep blowing nonstop. With this fuse in it causes no problems, but will it hurt the sound ect?
Which fuse is actually blowing? Its really not a good idea to run power to your amp through the car's fusebox.
If you're having problems at the amp.... well if your amp truly provides 750 watts rms then you'd need at least a 60 amp fuse both at the amp and inline close to the battery.
