rms is the power it can handle, peak is the number the manufacter puts on the box to make you think bigger is better. in other words rms is the correct power, peak is the selling power.

As other people have said, RMS is basically the amount of continuous power an amplifier can supply or a speaker can handle. Total watts is usually some ridiculous number derived for marketing purposes and doesn't really hold any water. Also, pay attention to the Total Harmonic Distortion (%THD) by which the RMS watts are measured. Any reputable company will have this cited near the wattage rating - the lower it is the better. Naturally, comparing different RMS ratings at different levels of THD can be a headache, so the CEA-2006 standard was set for measuring power. Only a few companies use this standard (Alpine is the only one that comes to mind), but it's worth knowing about.

RMS (root mean square) is the nominal power an amp produces or what a sub can handle.
Peak (or max) is a meaningless term as an amp rarely ever reaches peak and if it does, it's only for about 1/10 of a second.
I find it strange you ask this question when you answer a previous post with "...what ever the rms is on the box or in the manual you should match it with an amp, and don't worry about the peak power."

R.M.S. defined is root mean squared it is the continous average power. This is the spec you want to consider for amplifiers and speakers.
