[QUOTE="chris229, post: 59591, member: 542614"] crest factor???? what I was talking about in the other post?? in reference to music ----- if you where to put a sound through a device to look at the energy content of a song you would see the is and average amount of power then there is also peaks in power---drum kicks ---or just a peaks in energy. The crest fact is the measure of the peaks to the average energy. a crest fact of 10dBs on a 100W amp would look like ----full power 100W drum kicks with 10W average energy you see it the peaks are 10X the average power. SQ type test music can have 20dB crest factors. it would look like 100w kicks with 5W average power. This is also the reason you can run 2000W systems on 90A alternators. The reson being amp don't draw current like a toaster or blow drier unless you listen to test tones. if you listen to MUSIC most of the amps power is UNUSED. listening to MUSIC is ALSO why caps help the alternator load. The cap helps with the peak current and finally this is also why we must clip are amps-----so we can use more of the amps power for the AVERAGE content of the music. know one want to buy a 1000W amp and only use 100W of it.
