Installation Procedure/Connections
1.
Disconnect the NEGATIVE battery post connection and secure the
disconnected cable to prevent accidental reconnection during installation.
This is an essential safety precaution during installation!
2.
Connect the RED power lead to the positive (+12V) battery post.
4 AWG is
the minimum power wire size for this amplifier.
3.
An appropriate fuse (sold separately), such as the JL Audio Water-Resistant
Master MAXI™ Fuse Block (XD-MFBW-MAXI), at the main power wire(s) to
the amplifier(s) is vital for vehicle/vessel safety. This fuse must be installed
within 18 inches (45 cm) of the positive battery post connection. If this is
the only device connected to this main wire, use a 60A fuse. Do not install
the fuse until the power wire has been securely connected to the amplifier.
4.
Connect the BLACK negative ground lead to a clean, solid metal grounding
point near the amplifier. This can be to metal chassis ground, if available.
If no metal chassis ground is available, it may be necessary to make this
connection to the NEGATIVE battery post.
4 AWG is the minimum ground
wire size for this amplifier. All ground connections (source unit and
amplifiers) should be made at the same location.
5.
Connect the BLUE remote turn-on lead to the source unit’s positive (+12V)
remote turn-on output. If your source unit does not have a dedicated
remote turn-on output, the amplifier’s turn-on lead can be connected to
+12V via a switch that derives power from an ignition-switched circuit.
6.
Signal Input (Low-Level): Connect the amplifier’s RCA input jacks to the
source unit’s preamp level output jacks.
7.
Signal Input (High-Level): If your source unit does not offer preamp level
signal outputs, you can splice the speaker
output wires of the source unit
onto a pair of RCA plugs for each input pair or use the JL Audio ECS Speaker
Wire to RCA adaptor (XD-CLRAIC2-SW). Make sure to observe correct
polarity in making “High-Level Input” connections. Failure to do so will result
in a loss of signal (poor performance).
8.
Connect the speaker output leads to the corresponding speaker wires.
9.
Make necessary adjustments to the filter controls and input sensitivity.
10.
The amplifier’s subwoofer output level can be controlled from the front
of the vehicle/vessel with an optional remote level controller (sold
separately). Use the RBC-1 for standard (dry) installations or the M-RBC-1
for applications exposed to moisture. Connect the remote’s plug to the
amplifier’s harness-mounted RJ11 input jack. (Refer to Appendix B)
WARNING! Failure to make safe, tight, high-integrity power connections
can result in fire and extensive damage!
