Why do some amps have like 1000 watts but only 50W x 2 Rms @ 4 ohms like mine ? Then some like this one have 800 watts and 200W x 2 @ 4 ohms? After buying my amp I noticed this! At least it was cheap

P.S. It doesn't say my amp's RMS power on the site but it does in my manual.

 

b/c it's easier to sell a 1000w amp for a lower price than for the rms rating especially when you are looking at Pyramid amps. You get what you pay for.

 

Well, most places that do that advertize the highest possible power their maps are supossed to put out at the lowest impedence they're rated at. the 200Wrms @4ohm x 2 can only handle 4ohm Mono, or 2 Ohm Stereo, whereas the 50Wrms @4ohm x 2 can probably handle 1 ohm stereo/2 ohm mono... that'll theoretically double the power output...

but yes, typically you do get what you pay for...

 

there is no regulation on car audio. Do you really think a radio puts out 60w by 4. An amp company can put what ever they want on the cover just to sell uneducated people amps. People who know better alway look for the RMS number. Usually rms power is around 77% of peak power. A good amp that puts out 50 watts per channel will put out 200watts mono rms (cheater amps excluded) Peak power could exceed 300watts or more. Also distortion rate and dampening factor play a large role on how an amp sounds. They lower the distortion the better the higher the dampening factor the better. The a cheap amp might put out the 1000watts advertised but at a sky high distortion rate with little or no control of the woofer.
