How did you come up with the measurements 20x10.5x10?

cant be 10.5 x 10 its round so has to be the same !

Why does it say 500 watts on the subwoofer? But you say 600 watts

It's neither. Your lucky if you get 200 watts out of it but depends on which input you use and the radios output. I opened mind to see what the audio chips looks like and they are only rated at 150 to 200 watts max.

Why can’t I return this item ,it was wrong one

Ask the seller, there customer service isn't the best
