I am back with another installment of the random audio discussion to get our minds off of work/school/being bored @ home!

Today's topic:

LIES! How can a company like Pyle or Pyramid, even Sony advertise that their amps, speakers, and subs reach unreal wattage levels when it is physically and even theoretically impossible. Could that not be considered faulty advertising?

I saw a Pyramid 1000W amp @ an audio store the other day. They HAVE TO KNOW that it will never reach 1000W even in the perfect circumstances even for the smallest fraction of a second. They know this because they stick 2 x 25amp fuses on it. In a perfect 14.4 volt car, the fuses would pop before they got anywhere near 1000W, so 1000W is impossible as is. Watts = Voltage * Amperes. 1000W = 14.4V * 69.44A. At 12V you would need 83A. The highest the amp could put out before the fuses blew would be 720W @ 14.4 V. We all know that the amp would not even put that out though.

Could Sony advertise their new HD television does 1080i when they know it only could do 720? People would be angry!

Super cool the amp with liquid nitrogen or streams of compressed air.

Run the amps at the highest operating voltage possible.

Run a test tone at maximum RCA input voltage, Check maximum output voltage with clipping with no load presented to the speaker outputs.

Take the voltage and square it byitself then multiply by ohms.

You now have an impossible peak power rating.

Sad i know, but its slowly getting better out there, some of the shitty companys are actually including reasonable RMS ratings with their amps these days so things are starting to improve.
