500 watts Peak Power means that this amplifier may hit that wattage level for an instant. Its unlikely that it would do it more than once, if at all. ACTUAL wattage specs from Pyle:
Power Output: 500 Watts Peak Power
MAX Power Output: 50 Watt x2(@ 4 Ohm)
RMS Power Output: 35 Watt x 2 (@ 4 Ohm)
Even 50 watts seems dubious as the max power rating, but 35 watts RMS seems likely. I wouldn’t expect much more than that from this Pyle.
Pyle is all garbage. I’d really like to see it omitted from the selection on woot.
