Also, does this mean that since the subwoofer has its own amplifier, it wouldn't need power from an A/V receiver to run it? Thanks in advance for the answers.
Most subwoofers have a built in amplifier. 600w RMS means that this is the 'real' rating or what it is outputting most of the time on average, but in scenes of the most intense bass the amplifier can peak at 1500w in very short bursts. Since some amplifiers are rated only showing their peak watts, Epik shows you this statistic on theirs so that you know it can put out some serious watts when it has to.
The output from a receiver called "subwoofer" is an RCA line-level output meaning your receiver offers NO power but only a signal for the subwoofer to pick up on so if you want to run a subwoofer the easiest (and most common way to do so) is with a powered sub.
