Yeah, a 50a 120v circuit is a lot. You could feed it with a 50a circuit, but it doesn't need a 50amp circuit.
If I had one, and was pushing it encountering the occasional limit,.. I'd likely place it on a 20a, 120v circuit, with up-sized wiring (10awg for short runs, and 8awg for moderate runs, depending on distance) between the breaker and receptacle.
It plugs into a 20amp receptacle, so a 20 amp breaker is fine, ... however upsizing the wiring is important if you don't want any inhibiting voltage drop whatsoever. Be mindful a 20amp breaker can pass enormous amounts of current for short term needs.
For around a second or so, a breaker can easily pass up to 7x it's rated amount!
For a few brief seconds, it can still pass about 100amps!
The same breaker can allow about 2x it's rated amount for 20-30 seconds. 40amps, for 20-30 seconds ... that's a lot
These are huge amounts, and easily enough for this amplifier in normal HT, or music playback. Test tones, all bets are off ... besides, nearly all amps can't produce their rated amount continuously.
With these power hungry, LT'd multiple sealed sub systems for HT, it's prudent to lower individual loads by either utilizing 240v amplification, or spreading the load over multiple amplifiers, on multiple circuits. Or, examine how an IB alignment can produce full excursion levels with very modest amounts of power.
My quad 18 IB, cleanly hits ~125dB@20hz@1m@225w per driver! Just sayin'
Low compression, no voltage drop, and best of all, ... no LRSE
You don't need a 50amp breaker.
