    This may be a silly question, but the Manual specs says as follows:

    Recommended Fuse Size: ............ 2 x 20 amp ATO style


    Is that 2 x 20 amp fuses in series? Or parallel? Can I use a 40 amp fuse instead?

    its 2x20amps, cause if its like most amps it has a fuse box built in that u just replace the fuses with. But that also usually means it comes with fuses.

    Now if its a rare amp that requires a fuse outside on the line in then i'd still get 2x20amps. But seeing how it requires ATO fuses im pretty sure it has a built in fuse box

    The wiring needs to be fused at the battery, not to protect the amp but to prevent a fire in case of the wire being shorted to ground.

    The main wire fuse needs to be sized according to the wire gauge used. If you're running 8awg wire you dont want a fuse larger than about 60A. It doesnt need to match the fuse rating of the amp's internal fuses but shouldnt exceed the current capacity of the wire.
