  If your speaker system has an AC power supply of its own, you can use it. It should be having an AD-DC converter inside for its electronics. Just take care that your Remote control application doesn't consume current that could overshoot the internal power supply ratings. Since you said its a PC speaker, one idea would be to use the USB as source of power for your system.
  
  I don't think the power supply would be same for all wattage speakers. Because higher the wattage, higher would be the DC supply to the amplifier inside. But of course you can add a small power supply of your own for your system.

  Not necessarily, there are IR sensors available that work with 3.3V also.
