UHC5-UHC5- SUBWOOFER TERMINALS
Follow the polarity(+) (-) markings first. You
may want to experiment with reversing the (+)
and (-) connections to see which way sounds
best. The subwoofer channel is 1Ω stable, and
can drive up to four 4Ω subwoofers connected
in parallel.
UHC2UHC2- - SPEAKER TERMINALS
Follow the left, (L+) (L-), and right, (R+) (R-
), channel and polarity markings, making sure
they match the channel and polarity of the
connections at the speakers.
MULTIPLE SPEAKER
CONNECTION
PARALLEL- Each additional speaker decreases the load impedance
for the amplifier. The amplifier delivers more current and works
harder.
SERIES- Each additional speaker increases the load impedance for
the amplifier. Impedances higher than 8 ohms are rarely used for car
audio.
