choro yaar ......i let you know , same way some one will help me in knowing stuff
very easy example
you put DSL line
they claim 64KB/s is downloading speed and you get a pakage of 256kbps speed
when you download files
you get continous 63~64 kbps file transfer rate
now you think it was said it was a line of 256kbps
similarly
you get 1000W amps ( same 256 pakage)
and you get
400Wrms ( same 64 kbps file transfer speed)
now 400W watts will be continous power deliver to subwoofer
where 1000W writen just to impress you it doesnt count
An amplifeir written 5000W peak , 300Wrms
and
another amplifier written 400W peak , 300Wrms
there power will be same
