RMS means root means square, which is .808 of a amps peak output. It directly correlates to a speakers wattage capability . What you need to know is if the amplifier is rated watts per channel into a 8,4,2 ohm load & +/- .5% total thd(total harmonic distortion) the lower the better, or whatever the amps output states & the speakers capacity should match. This is not the gospel, but it is 95% correct. Basically don't buy speakers at a autoparts store & spend $35-60 a pair & you should be okay
