THANK YOU
for choosing the JBL BassPro. BassPro has been designed to
provide the kind of high-performance low-frequency reproduction
that used to require big, clumsy enclosures, large amplifiers, and
complex installation. To ensure maximum performance, we
strongly recommend that installation be entrusted to a qualified
professional.
WARNING
Playing loud music in an automobile can permanently damage
your hearing as well as hinder your ability to hear traffic. We
recommend using low volume levels while driving. Harman
International accepts no liability for hearing loss, bodily injury or
property damage resulting from the use or misuse of this product.
INSTALLATION
Choosing a mounting location
Choose a location that doesn’t interfere with the loading or
unloading of cargo, fold-down rear seats, or opening or closing of
the trunk lid. The best location is likely to be the front or rear
corner of the trunk or luggage compartment. These locations, in
addition to being out of the way, will provide the best sonic
reproduction in the 60Hz 100Hz range because the output of
the woofer will be “corner loaded” against the walls of the vehicle.
In any case, the BassPro must not interfere with the safe
operation of the vehicle.
CAUTION: Make sure mounting screws will not puncture wiring
harnesses, brake or fuel lines, or the vehicle’s fuel tank. Some or
all of these may be located behind or under the mounting surface.
Mounting BassPro
IMPORTANT: Disconnect the vehicle’s negative (–) battery
terminal before beginning the installation.
NOTE: If you are using only the BassPro’s line-level (RCA) inputs,
you must connect the remote wire from the BassPro to the
system’s head unit so BassPro will turn on and off with the
system. If you will be using the speaker-level outputs from your
head unit, you do not need to connect the remote output. The
BassPro’s speaker-level inputs will sense voltage on the speaker
wires and the BassPro will turn itself on. (See Audio Sense
Switch, below.)
Input Connections
Connect the subwoofer output from the
source unit to either the left or right
line-level input. If your source unit does
not have a dedicated subwoofer output
you can connect the rear left/right
outputs to the BassPro’s left and right
inputs.
If your source unit doesn’t have
line-level outputs you can use the
included speaker-level input harness to
connect the BassPro to the source
unit’s speaker outputs. See the
illustration for the wiring configuration.
