FM SUB - JBL Audio User Guide / Operation Manual. Page 3

Speakers and electronics ter-
minals have corresponding (+) 
and (–) terminals. It is impor-
tant to connect both speakers
identically: (+) on the speaker
to (+) on the amplifier and (–)
on the speaker to (–) on the
amplifier. Wiring “out of phase”
results in thin sound, weak bass
and a poor stereo image.

The wires for both speakers
should be the same length. If
one speaker is placed closer to
the amplifier than the other,
hide the excess wire behind 
the wall.

The FM8SUB has two speaker
connections. Connect one set of
terminals, along with your left

satellite to the left channel of
your amplifier. Connect the
other set of terminals, along

with your right satellite to the
right channel of your amplifier.
