if a speakers rms is say 350watts and their rms is 100 watts, what would happen if say i put 160watts rms into them or would they work fine if not better than just giving them 100 watts rms
He means a 350 watt peak rated speaker, with a true 100W RMS rating. The 100W RMS rating is thermal, meaning it can withstand the heat of 100 watts of power. Anything above that is risking it, but remember that a 100W RMS amplifiers is only going to produce it for a little while due to the dynamic nature of music. You'll rarely use all that power. That being said, if you're careful not to overdrive the speakers, a 160W RMS amplifier won't hurt a bit.
RMS is continuous, or what your amplifier's RMS should not exceed with that speaker. the peak rating isn't that useful but it's a momentary rating, or how much the speaker can handle for a brief exposure without pretty much cooking. stick to continuous or RMS ratings for amps and speakers both
