Thank You
for selecting a
JBL GT Series Powered
Subwoofer System. JBL’s history
of high performance and innova-
tion goes back 50 years, yet the
only things old-fashioned about
the GT Series products are the
craftsmanship and attention to
detail that go into each one. The
model you have chosen delivers
exceptional performance in a
compact package. With proper
installation and use, it will pro-
vide many years of listening
pleasure.
GT Powered Subwoofer
Features
Your Powered Subwoofer fea-
tures a built-in amplifier and
electronic crossover capable of
supplying 80 watts of power to
the specially designed Dual
Voice Coil 2-ohm woofer. The
built-in crossover features an
adjustable low-pass filter and
level, facilitating simple match-
ing to virtually all main speaker
systems. In addition, this unit
will accept signals from either
preamp level, or speaker level
inputs, allowing connection to
virtually all source units whether
supplied by the car manufac-
turer or purchased separately. A
built-in music sensing circuit will
turn the unit on in the presence
of a music signal without the
need to run a separate remote
turn-on wire. The unit will turn
off automatically a few minutes
after the music stops to conserve
battery power.
