About 2 0 operation
Your CHAOS EXXTREME II amplifier
has been designed to operate
efficiently at loads down to 2 0.
This means that you can install four
8 0 speakers per channel, when
using parallel wiring.
Increasing the number of woofers per
channel
at low frequencies (below
1OOHz) produces an acoustic coupling
effect. This
acoustic coupling effect
increases
your power output by about
3dB per speaker, or the equivalent of
an additional 1 OW per speaker.
When
operating at 2 0, 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 Q load.
If you lack adequate current, your
music reproduction will be distorted.
