8 gauge is sufficient for around 30-40 amps...50 amps is pushing it.

How much current does your amp draw? Output doesn't determine what size wire is needed, its based on amp draw.


up to 50 amps I say 8 gauge is fine

50-90 4 gauge

100+ 0 gauge

if the amp has a 30A fuse, you should be fine with 8ga wire.
