BASSPRO II (serv.man9) - JBL Car Audio User Guide / Operation Manual. Page 4

Connecting power to BassPro II is 
shown in Figure 7. Please observe 
the following installation tips:

When using the high-level input con-
nections, BassPro II will automatically
turn on when you turn on your radio. 
In this case, the remote (REM)
connection is not needed. Use at least
#20 AWG speaker wire for speaker-level
input connections.

Use at least #12 AWG wire for the
Positive Battery (BATT +12) and Ground
(

) connections. If needed, use at least

#20 AWG wire for the remote (REM)
turn-on connection.

Connect BassPro II’s “BATT +12V” 
terminal directly to the battery’s positive
(+) terminal. Install a fuse holder, with a
20A fuse, within 18" of the battery’s
positive (+) terminal.

Route all power wires through a
grommet in the vehicle’s firewall. If a
factory grommet is not available, install
one.
Connect a short ground wire from
BassPro II’s ground terminal ( ) to the
nearest bare metal surface. For a good
connection, use sandpaper to clear
paint from the metal surface and use 
a screw with a lock (star) washer.

The remote (REM) connection requires
a +5 to +12 Vdc signal for BassPro II
to turn on when using the line-level
connections. Most head units with 
preamp outputs provide this remote
voltage signal. As an alternative, 
connect this terminal to a switched
ignition circuit.
