Hey what is the true wattage of the Orion 4002. On some sites it says 100 x 2 @4 and on others it will say 150 x 2 @4. Which is correct? I am going to be using it on a set of cdt cl61A components with tw 24 tweeters, 130 watt rms.
It will be fine on those speakers regardless of the actual power since you'll never see all of it anyway.
However to answer your question, IIRC the last series of Orion amps were rated to double their power when run @ 2 Ohms or bridged and were named according to total power at the lowest rated impedance with the last number in the model number being the number of channels. That would make the 4002 a 2x100 amp into 4 ohms or 2x200 into 2 ohms or 400x1 into 4 ohms when bridged.
