PROTECT YOUR HEARING!
We value you as a long-term customer. For
that reason, we urge you to practice restraint in
the operation of this product so as not to damage
your hearing and that of others in your vehicle.
Studies have shown that continuous exposure to
high sound pressure levels can lead to permanent
(irreparable) hearing loss. This and all other
high-power amplifiers are capable of producing
such high sound pressure levels when connected
to a speaker system. Please limit your continuous
exposure to high volume levels.
While driving, operate your audio system in
a manner that still allows you to hear necessary
noises to operate your vehicle safely (horns,
sirens, etc.).
SERIAL NUMBER
In the event that your amplifier requires
service or is ever stolen, you will need to
have a record of the product’s serial number.
Please take the time to enter that number in
the space provided below. The serial number
can be found on the bottom panel of the
amplifier and on the amplifier packaging.
Serial Number:
INSTALLATION APPLICATIONS
This amplifier is designed for operation in
vehicles with 12V, negative-ground electrical
systems. Use of this product in vehicles with
positive ground and/or voltages other than 12V
may result in damage to the product and will void
the warranty.
This product is not certified or approved for
use in aircraft.
Do not attempt to “bridge” the outputs of this
amplifier with the outputs of a second amplifier,
including an identical one.
PLANNING YOUR INSTALLATION
It is important that you take the time to read
this manual and that you plan out your
installation carefully. The following are some

ProduCt desCriPtion
The JL Audio HD900/5 is a very powerful
and compact five-channel amplifier utilizing
patented Single Cycle Control™ Class D
technology for all channels. This groundbreaking
technology delivers reference-grade, full-
range sonic performance while requiring
far less current from the vehicle’s electrical
system than a conventional amplifier.
JL Audio’s exclusive R.I.P.S. power supply
design optimizes the output of each channel
section for any impedance between 1.5 and 4
ohms per channel (3-8 ohms bridged on front and
rear sections) allowing you to get full use of the
HD900/5s performance capabilities with a wide
range of speaker systems.
The tightly regulated power supply design also
means that the HD900/5’s clean power output
capability remains stable over a wide range of
vehicle voltages, resulting in enhanced fidelity.
The HD900/5 flexible, studio-grade signal
processing allows it to be deployed in several
different system configurations:
1) As a five-channel amplifier in a bi-amplified
system, driving four satellite speakers (100W x
4), plus a subwoofer system (500W x 1).
2) As a very powerful three-channel amplifier
in a bi-amplified system, driving two satellite
speakers (150W x 2, bridged), plus a subwoofer
system (500W x 1).
3) As a five-channel amplifier in a tri-amplified
system, driving two tweeters (100W x 2), plus
two woofer/mids (100W x 2), plus a subwoofer
system (500W x 1). An external 2-way
crossover is required for this application.
The HD900/5s f lexible input and crossover
sections permit operation with a wide variety
of source units and system configurations.
It can be operated with a single pair of
stereo inputs, with two pairs of stereo inputs
(front and rear) or with separate inputs for
its front, rear and subwoofer channels.
As we said, it’s very flexible.
