About 2 Ohm operation
Your ARMOR amplifier has
been designed to operate efficiently
at loads down to 2 Ohms. This
means that you сап install four
8 Ohm speakers per channel, when
using parallel wiring.
DouЫing the number of woofers
produces an acoustic coupling
effect. This acoustic coupling effect
increases the output Ьу about ЗdВ
for each douЫing of the number
of woofers.
When operating at 2 Ohms, the
amplifiers will increase their output
power Ьу approximately 50%. The
current draw wi/1 also increase Ьу
about the same amount, so Ье sure
уои have enough current to run the
amplifiers into а 2 Ohm /oad.
lf you lack adequate current, your
music reproduction will Ье distorted.
