question about installation of 20 amp wall plug


I bought a replacement wall plug that is rated 20 amps. I installed it from a 15 amp circuit breaker, in the add it said it was ok to use in 15 or 20 amp. I pluged in a cheap intergraded amp to it and it and my speakers started popping and the amp started to smoke, I unplugged it right away. Was I wrong to assume that it would be ok coming from a 15 amp circuit, can anyone tell me what I did wrong, thanks

Thanks for all of your help. I will get a volt meter and try again. I have installed 15 amp plugs before with no problem and I thought I had this one installed right but I guess not. The intergraded is not worth fixing. Any way I will reinstall after I get the volt meter,
