Does an amp actually put out the rms it says it does? example: 500 rms X 1 at 4 ohms

Actually an amp that says it puts out 500w rms will actually do more.

Use this formula:

Ap: Actual Power

rms: rms value

La: length of amp

P: purchase price

Ap = {(10^7 x P) / [(5.42 x rms) / (721.98 / La)] / (rms x 100)} x 4

so let's say:

rms: 500w

La: 12

P: $299

{(10^7 x 299) / [(5.42 x 500) / (721.98 / 12)] / (500 x 100)} /x 4

[(2990000000 / 39.225) / 50000] x 4

(7622689.611 / 50000) x 4

152.45 x 4

609.8w rms

That formula only works for black and copper colored amps. For chrome amps you gotta divide by 4.

I thought it was 3.5. d@mn so all this time i was telling people the wrong numbers. I can't beleive i let myself overrate them.

assuming you are getting a steady 14.4v (or whatever) rated voltage is, it should - if you are running another amp and your total current draw surpases the ability of the alternator then no- lenght and size of wire play a big part also- in other words in a 'perfect world' yes it should, but very few live in that world-

It also sometimes works for dark gray and gold colored amps... but that's only if they have no logos on them.

and subtract 5 for every time the amp's power is printed in BIG HUGE BOLD NUMBERS on the amp case...

What about Brand name ?

IIRC you divide the price by the value of the letters

Ex. A=1 B=2 C=3 ect.

P.S
