RMS is how much the speakers can handle constaintly, this is the most important one. Peak/Max is how much it can handle in a quick burst like when the bass hits.

Think of it like lifting weights. RMS is like how much you can lift in a set. Lets say you can lift 80lbs in a set of 10 times each set. Peak/Max is how much you can lift one time only like whats the most you can lift.

Awsome analogy, I understand now. thanks bro :tu








would rep but i must spread

as far as Head Unit's and amps go-Peak = a burst of power which comes in a sudden bass hit,high note or what ever.The rms provided by a Head Unit/Amp is the all the time power.

RMS = What you get 90% of the time

Peak = What you get 10% of the time

100% WRONG WRONG WRONG!

Power RATINGS:
RMS= what you SHOULD get with an unclipped -0db sine wave, continuous, with properly set gains. (Note: This is again, rated power.... not ACTUAL power)
Peak/Max= Should be: amount of power you can get on a transient (instant jolt of power... the smack of the drum, a power chord, etc...) But that is almost NEVER true for an amplifier.... Peak/Max on an amp.. is often either A: the limit of the power supply considering output efficiency.... or B: maximum 100% square wave output rating...

ACTUAL power:
RMS= continous power CAPABILITY.
REAL WORLD RMS or RMS RMS...... 10-15% of RMS with gains set properly...
(think about it.. if your deck goes up to 100... and your amp is set correctly.. so 100 on your deck is 100% of amp's RMS capability... and its a 100 watt RMS amp).. you will only ever see 100 watts with the deck at 100... AND with a -0db sinewave or waveform.

Now.. -0db is the LOUDEST signal possible on a CD...
real world, expected output of a 100 watts RMS amp... continously averaged over 10 minutes of music or so? 10-15 watts.

Actual Peak: a full voltage swing from one side to the other.. and back....

Because if people got RMS ratings all the time... there couldn't be any quite spots in the music... it would ALL be the same volume.
I don't know about you, but lots of the crappy top40 music coming out these days was recorded so "Hot" (technical term for they're amplifying the shit out of it when they mix it so that its louder than it should be, but much less dynamic) that it sounds like ass on a good stereo.
