Product Description; Typical Installation Sequence - JL Audio RD500/1 Owner's Manual

PRODUCT DESCRIPTION

The RD500/1 is a monoblock amplifier
utilizing JL Audio NexD™ high speed switching
technology to deliver outstanding fidelity
and efficiency.
The RD500/1 can be operated with a wide
variety of source units and system configurations.
Its frequency response is limited to the
range below 500 Hz. It is not designed for
driving midrange speakers or tweeters. Every
aspect of its operation has been optimized
for low-frequency amplification.

TYPICAL INSTALLATION SEQUENCE

The following represents the sequence
for a typical amplifier installation, using an
aftermarket source unit or OEM Interface
processor (like the FiX™ 82 or FiX™ 86).
Additional steps and different procedures may
be required in some applications. If you have any
questions, please contact your authorized
JL Audio dealer for assistance.
1) Disconnect the negative battery post
connection and secure the disconnected cable
to prevent accidental reconnection during
installation. This step is not optional.
2) Run 4 AWG copper power wire from the
battery location to the amplifier mounting
location, taking care to route it in such a way
that it will not be damaged and will not
interfere with vehicle operation. Use 4 AWG
or larger copper power wire and a fused power
distribution block if additional amplifiers are
being installed with the RD500/1.
3) Connect the power wire to the positive battery
post. Fuse the wire with an appropriate fuse
block (and connectors) within 18 inches (45
cm) wire length of the positive battery post.
This fuse is essential to protect the vehicle.
Do not install the fuse until the power wire
has been securely connected to the amplifier.
4) Run signal cables and remote turn-on wire
from the source unit to the final amplifier
mounting location.
5) Run speaker cables from the speaker systems
to the amplifier mounting location.
6) Find a good, solid metal grounding point
close to the amplifier and connect the
negative power wire to it using appropriate
4 | JL Audio - RD500/1 Owner's Manual
hardware (use of the JL Audio ECS master
ground lug, XB-MGLU is recommended). Use
4 AWG copper wire, no longer than 36 inches
(90 cm) from the amplifier to the ground
connection point. In some vehicles, it may be
necessary to upgrade the battery ground wire.
(See page 5 for important notice).
7) Securely mount the amplifier and remove
the top control panel cover using the
supplied 2.5 mm hex wrench.
8) Connect the positive and negative
power wires to the amplifier. A fuse
near the amplifier is not necessary if
the RD500/1 is the only device being
run from the fused main power wire.
If the fused main power wire is shared
by the RD500/1 and other amplifiers
or devices, fuse each amplifier/device
within 12 inches (30 cm) of wire length,
via a fused distribution block or multiple
individual fuse blocks/on-board fuses.
9) Connect the remote turn-on wire to the
amplifier or configure the "Turn-On Mode"
switch for automatic turn-on.
10) Connect the input cables to the amplifier.
11) Connect the speaker cables to the amplifier.
12) Carefully review the amplifier's control
settings to make sure that they are set
according to the needs of the system.
13) Install the power wire fuse (50A for a single
RD500/1) and reconnect the negative battery
post terminal. Install the fuse (50A) near the
amplifier (if applicable).
14) Turn on the source unit at a low level to
double-check that the amplifier is configured
correctly. Resist the temptation to crank it up
until you have verified the control settings.
15) Make necessary adjustments to the
input sensitivity controls to obtain the
right overall output and the desired
balance in the system. See Appendix
A (page 12) for the recommended
input sensitivity setting method.
16) Replace the top control panel cover using the
supplied 2.5 mm hex wrench.
17) Enjoy the fruits of your labor with your
favorite music.
