determine what the impedance match is on the amplifier or speaker terminals. look on the back of your speakers. if the amp 's output is 8 ohms then your speakers should be 8 ohms. if you parallel the speakers then the impedance will be one-half or 4 ohms and gives an imbalance to the output transformer or transistors in the final amplifier. this imbalance will burn out an audio output transformer or transistor. surround sound uses four speakers from four outputs on an amplifier. you can't duplicate surround sound just by hitching up four speakers to your two outputs.
