Black Friday is Friday, November 27, 2026. Amazon’s Black Friday deals run November 19–30, through Cyber Monday, from 12:01 a.m. PT (3:01 a.m. ET) on November 19. , Amazon lists Rockville RCS180-6 180W 6-Zone 70V Commercial Amplifier at $219.95, with no deal badge.
Things of the same kind for at least 10% less than $219.95, with the attributes the retailers describe differently. Their words, not our judgement: we compare listings, we do not test products.



A power rating means most when stated in full: watts per channel at 8 ohms, across 20 to 20,000 Hz, at a stated distortion, with all channels driven. Polk Audio warns that a figure at 1 kHz with one channel driven overstates real power.
Class D amplifiers waste much less power as heat than Class A, AB or B designs, Analog Devices says, so they run cooler.
