you cant. or try finding a 1 ohm speaker.
id guess its giving a bit under 10-15rms w.

 

I'm big on 2 and 3 way speakers because of the range and accuracy of sound reproduction. Those paper speakers sound tone deaf and dull. How many RMS is the stock amp? Can it power Infinity Kappa or Polk speakers that require 8 rms min? Supposably the Bose system is high watts but are they RMS or peak? Can anyone suggest a way to upgrade the speakers without changing the amp? Id like to do components in the front and 2 or 3 ways in the rear.
