About 2 Ohm operation

Your CHAOS EXXTREME amplifier has been designed to operate efficiently at loads down to 2 Ohms. This means that you can install four 8 Ohm speakers per channel, when using parallel wiring.

Increasing the number of woofers per channel at low frequencies (below 100Hz) produces an acoustic coupling effect. This acoustic coupling effect increases your power output by about 3dB per speaker, or the equivalent of an additional 10W per speaker.

When operating at 2 Ohms, the amplifiers will increase their output power by approximately 50%. The current draw will also increase by about the same amount, so be sure you have enough current to run the amplifiers into a 2 Ohm load.

If you lack adequate current, your music reproduction will be distorted.
