Quick noob question. Inline fuses.

[johnnyvolcom5 10+ year member]

Ok, so when running power wire to amp, you should always use an inline fuse correct? The inline fuse amperage is supposed to match the fuses on amp right? Like my amp has three 30 amp fuses.....so i would need an inline fuse of 90 amps? AM i wrong, cause i can only find 80 amp or 100 amp fuses......should i put an 80 instead of 90?

Thanks...and did a quick search for "inline fuse" and didnt find a clear answer

The fuse by the battery is for the wire not the amp. It dont hurt to go the same as the amp but its meant to protect the wire from flaming up not the amp. If your amp has onboard fusing you dont have to fuse it. If it dont you fuse the wire by the amp to match the amp also.
