600W Full-Range 2-Channel Class D Amplifier
with Integrated DSP
Installation Applications
This amplifier is designed for operation with 12 volt, negativeground electrical systems. Using this product in systems 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.
Product Description
This is a two-channel, full-range Class D amplifier equipped with the
second generation of JL Audio’s NexD2™ high-speed switching technology.
It is engineered to deliver reference-grade audio amplification with
outstanding efficiency and unprecedented, built-in processing power.
Instead of traditional analog processing controlled by knobs and switches,
VXi amplifiers feature an integrated DSP (Digital Signal Processor). The
amplifier and its integrated DSP are configured using an external device
(PC, Tablet or Phone), with the appropriate JL Audio TüN™ application
installed. (See What is TüN? section for more info.)
Planning Your Installation
It is important that you take the time to read this manual thoroughly
and that you plan your installation carefully. It is very easy to damage
expensive vehicle systems in modern automobiles. Never assume that you
have found appropriate wires without consulting a reliable wiring diagram
or without analyzing with proper test equipment. If you are uncomfortable
or unfamiliar with reading diagrams or testing methods, please enlist the
services of your authorized JL Audio dealer to perform the installation.
Your authorized dealer has the training, expertise and installation
equipment to ensure optimum performance from this product. The
following are some considerations that you must take into account when
planning your installation.
Safety Considerations
• Install your amplifier in a dry, well-ventilated location that
does not interfere with your vehicle’s safety equipment
(air bags, seat belt systems, ABS brake systems, etc.).
• Do not mount the amplifier in the engine
compartment or in any areas of extreme heat.
• Securely mount the amplifier so that it does not come
loose in the event of a collision/sudden jolt or as a result
of repeated vibrations during normal operation.
• Check before drilling to make sure that you will not be drilling into
a fuel tank, gas/brake line, wiring harness, or other vital system.
• Do not run system wiring outside or underneath the
vehicle/vessel. This is an extremely dangerous practice,
which can result in severe damage/injury.
• Take the necessary precautions when making
connections to the vehicle’s battery.
• Protect all system wires from sharp edges by carefully routing them,
tying them down and using grommets and loom where appropriate.
• Secure all wiring as needed, using cable ties or wire clamps
to protect them from moving parts and sharp edges.
Cooling Efficiency Considerations
The outer shell of your JL Audio amplifier is designed to remove heat
from the amplifier circuitry. For optimum cooling performance, this outer
shell should be exposed to as large a volume of air as possible. Enclosing
the amplifier in a small, poorly ventilated chamber can lead to excessive
heat build-up and degraded performance. If an installation calls for an
enclosure around the amplifier, we recommend that this enclosure be
ventilated with the aid of a fan. In normal applications, fan-cooling is not
necessary. If mounting the amplifier under a seat, make sure there is at
least 1 inch (2.5 cm) of space above the amplifier’s outer shell to permit
proper cooling.

Power Connector
T he VX600/2i’s “+12 VDC” and “Ground” connections are designed to
accept 4 AWG copper wire. Note: Copper Clad Aluminum (CCA) wire is not
recommended. 4 AWG is the required copper wire size for this amplifier.
8.72 in
222 mm
6.62 in
168 mm
5.53 in
141 mm
Run copper wire from the positive (+12V) battery post to the amplifier mounting location. If additional amplifiers are being installed, run
the appropriate gauge copper wire for the combined, maximum current draw, and install a fused distribution block near the amplifiers.
An appropriate fuse (sold separately) at the main power wire(s) is
vital for vehicle safety. This fuse must be installed within 18 inches
(45 cm) of the battery post connection. If this is the only device connected to this main wire, use a 50 A fuse. Do not install the fuse until
the power wire has been securely connected to the amplifier.
The ground connection should be made to a clean, solid metal
grounding point using copper wire, and kept as short as possible.
The metal surface of the grounding point should be sanded to create
a clean, metal-to-metal connection. For optimal grounding, we
recommend using a JL Audio ECS master ground lug (XB-MGLU). All
ground connections (source unit and amplifiers) should be made
at the same location.
The remote connection should be made to the source unit’s positive
(+12V) remote turn-on output. If your source unit does not have a
dedicated remote turn-on output, consider one of the alternative
turn-on options. (See Turn-On Mode section for more info.)
Analog Input/Pre-Out Harness
The Analog Input Harness accepts the following connections:
Line-Level Analog Inputs: Two female RCA jacks feed a differentialbalanced input section, providing a high degree of input flexibility, and
retaining superior noise rejection. This type of input architecture also
allows the VX600/2i to cleanly accept any analog audio signal up to 16
VRMS, without using a line-output converter.
9.81 in
250 mm
Preamp Outputs: Two female, RCA jacks deliver line-level, analog audio
outputs (Max 4 V RMS) that are compatible with most types of aftermarket
equipment. These are configured with the TüN™ Software Interface.
Remote: This connection provides a positive (+12V) turn-on voltage
(475 mA limit) to activate other aftermarket equipment (similar to an
aftermarket head unit’s remote turn-on lead).
2.12 in
54 mm
Valet: When connected to negative ground, this connection activates the
Valet Mode Preset and will remain active until the ground connection is
removed. This preset is configured using the TüN™ Software Interface and
will override any DRC controlled preset.
Corner Cap Installation and Removal
The corner caps are designed to conceal the amplifier’s mounting holes
and hardware. To install, simply press a corner cap into each mounting
hole. To avoid scratching the amplifier’s chassis during removal, use the
included, plastic corner cap tool and lift below each cap.
Making Connections
VXi amplifiers utilize removable plugs and harnesses to make the
following connections:
• Power Connector
To connect the power, ground and remote turn-on wires to the amplifier,
back out the set screws on the connector using the supplied hex
wrenches. Strip back 3/8 inch (10 mm) of insulation from the end of each
wire and insert the bare wire into the receptacle on the power connector
plug, seating it firmly so that no bare wire is exposed. While holding each
wire in place, tighten each set screw firmly, taking care not to strip the
head of the screw. Install the power connector by plugging it into the
amplifier’s power connector receptacle, pushing firmly.
nalog Input/Pre-Out Harness
This harness includes connections for Signal Input (RCA plugs), Preamp
Outputs (RCA plugs), Remote Turn-On Output (wire lead) and Valet Input
(wire lead). Select either the included black hex cap machine screws or
the silver thumbscrews to secure the Analog Input Harness connector to
the amplifier.
• Speaker Output Harness
This harness includes output wire leads to connect with speaker cables.
Turn-On Mode
VXi amplifiers can be switched on and off using one of three methods,
configured by the “Turn On Mode” setting in the TüN™ Software Interface.
Refer to the table below for detailed info and decide which option is best
suited for your specific system.
