Do you understand wiring at all? You do not have 14 channels. You still have 7 at most. You can hook up 100 speakers to output of the amp and it will still be 1 channel. Also, you do understand that speakers have and impedance don't you? Amps can only play down so low before they overheat. Also, you understand that the additional speakers will take up additional volume in the room? Most every member here is also concerned with looks to some extent. Also the price of the extra sets. Don't forget setting up a sound stage so that it sounds good.
