Ok, just wonderning what do they mean when Ford says that teh Futura gets a 40w Stereo. Is 40w the overall power ie 10w a speaker if theres 4 speakers or is it 40w x 4.

Hey,

Its probably a measly 10W per speaker.... and i wouldn't bet on it being an RMS figure.

RMS is the continuous power handling of the deck/amplifier. Most figures that are thrown around by people are the PMPO (peak) power figures. Most of the units that quote these cant deliver that power for a 10th of a second before they die.

Cheers

Good stuff.

As for the ratings, I dunno. IMO it doesn't really matter as long as it goes loud... :s6: :s6:

Odds are it can put out 40w RMS maximum, split amongst however many speakers in the car (6 in the futura?). Ford usually advertise RMS, whereas plenty of other places advertise PMPO. If it was 40w PMPO, then you've got 6 very weak speakers, no matter how they are setup.

The factory speakers in falcons (pioneer i think) are usually fairly loud, so I'd say it's 40w RMS. But I doubt it would be 40w x 4.

Can anyone correct me?

Yeah could be right, gotta say stock for stock the ford stereo sounds better than other brands. Well if it's right then i've upgraded from 25w RMS to 60w RMS.

I am by no means an expert in this area but a few things being said are bothering me.

Correct me if I'm wrong but......

The power rating of a head unit has nothing whatsoever to do with what speakers are attached to it.

Speakers are loud if there are efficient, no matter what their maximum rated power handling capability.

NO WAY will a factory head unit (or any aftermarket one that I know of) put out a genuine 4x40W RMS. Even 4x10W RMS is very good for a head unit.

Futura97 · 02-13-2002, 21:05

I think its just the rating of the head unit. 40W is the power that the head unit pumps into the speakers. This 40W is likely to be max so RMS would most likely be 17-20W.

Did you know that for every double in wattage you only get a few dB increase in volume. Eg - going from 20w to 40w you only get 2-5dB increase in loudness.

cheers
