CONNECTIONS
About Power and Ground Connections:
The red B+ wire and the black ground wire should be connected directly
to the battery terminals in your boat. If your boat has a two-battery system,
connect the red and black wires to the battery that provides power for
your boat’s accessories rather than the battery that provides power to
start your boat’s motor. JBL’s MPS1000 is designed to shut off if it senses
that your battery’s voltage has fallen below 10 volts, in order to prevent
your battery from becoming fully discharged while you’re on the water.
Power Connection
Connect power, ground and remote turn-on signal to the MPS1000,
as shown in Figure 3. Also observe these installation tips:
• Use at least #12 AWG wire for the +BATT (+12 Vdc) and GND
(ground) connections. If needed, use at least a #20 AWG wire for
the REM (remote) connection.
• When routing power, ground, remote and signal cables, ensure that
wires are not able to become entangled with cargo, control cables,
the boat’s motor, passengers’ feet or any other object that could
become a safety hazard.
• Install a fuse holder with a 30A fuse within 18" of the b
terminal (see Figure 5).
• The REM connection re5 to +12 Vdc signal for the MPS1000
to turn on. Most head units with preamp outputs provide this remote
voltage signal. If the speaker-level inputs are used, a remote connec-
tion is not required, since the Auto Turn-On feature will sense voltage
on the speaker wires to automatically turn on the MPS1000.
Connecting the Signal
The MPS1000 includes a 2-channel speaker-level input and a 2-channel
line-level input. Either input connection type may be used. If you choose
the RCA-type plug connection, you must connect the remote turn-on
wire. Follow the diagram below to connect signal to your MPS1000.
