1. ## does an amp really put out what it says in rms????

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.

you guys have got to be kiddin me.......

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...

**** the ****ing **** *** ****ing amps.....go **** yourself in the ****ing *** you little *****...who cares about rms, you like your ****ing system or not, thats what ****ing matters....punk *****

IIRC you divide the price by the value of the letters
Ex. A=1 B=2 C=3 ect.
P.S
*******<-- not cool
