Basspro 8 Subwoofer
The package includes a wiring harness that features all necessary wires for power,
ground, and signal, and plugs into the “INPUT” connector on the back panel of
the Basspro 8. It also includes a pair of RCA adapters for use with speaker-level
inputs.
THANK YOU for choosing the JBL Basspro 8 powered subwoofer. To ensure
maximum performance, we strongly recommend that you have it installed by a
qualified professional – while these instructions offer general installation guidance,
they do not show specific installation methods for your particular vehicle. If you do
not have the necessary tools or hands-on experience, do not attempt the
installation yourself; instead, ask your authorized JBL car-audio dealer about
professional installation options.

FOR POWER
Connect the end of the red 16-gauge power wire to your vehicle’s + (positive)
battery terminal. Note: If an extension cable is necessary because of your
mounting location, we recommend that you connect the extension to the power
wire using solder. You must also install a fuse holder with a 10A fuse in-line and
within 18" of the battery.
FOR GROUND
Connect the 16-gauge black ground wire to a solid, metal point on the vehicle’s
chassis using a ring terminal. Use sandpaper to clear the paint from the metal
surface at the chassis location. Use a star-type lock washer to secure the wire.

INSTALLATION
IMPORTANT: Disconnect the vehicle’s negative (–) battery terminal before
beginning the installation.
• Always wear protective eyewear when using tools.
• When making electrical connections, make sure they are secure and
properly insulated.
• If you must replace the fuse, be sure to use the same type of fuse and
current rating as that of the original.
CHOOSING A MOUNTING LOCATION
Choose a location that doesn’t prevent you from loading or unloading cargo,
interfere with fold-down seats, or keep you from being able to open or close the
trunk lid, or interfere with the safe operation of the vehicle.
Basspro 8 WIRING
You’ll make all signal and connections, and adjust all settings at the panel on the

uncouple the bullet connector on the blue/white wire, and connect the longer wire
marked with “REMOTE IN” to the remote output wire on your source unit.

If you’re using speaker-level inputs to provide signal to the Basspro 8 (see below), you
must leave the bullet connector coupled so that the blue/white wire makes a loop.
When you’ve made all the necessary power and signal connections to the
Basspro 8 wiring harness, plug the harness into the input marked “INPUT”.
