Product Description

This is a six-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 TuN™ application installed. (See What is TuN? 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 manage 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 (in hope, cost-holt systems, ABC brake systems, etc).

(air bags, seat belt systems, ABS brake system) Do not mount the amplifier in the engine.

do not mean 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 pretia

vehicle/vessel. This is an extremely danger 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.

JL Audio Badge

To complement the amplifier's mounting orientation, the logo badge includes a recessed key feature allowing it to be affixed at 90 degree increments on the amplifier's top. To install, remove the adhesive backing and press the badge at the desired orientation.

1 Power Connector

The VX600/6i'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

A. 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.
B. 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.
C. 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.
D. 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.)

2 Analog Input/Pre-Out Harness

The Analog Input Harness accepts the following connections:

Line-Level Analog Inputs: Six female RCA jacks feed a differential-balanced input section, providing a high degree of input flexibility, and retaining superior noise rejection. This type of input architecture also allows the VX600/6i to cleanly accept any analog audio signal up to 16 VRMS, without using a line-output converter.

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).

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:

•PowerConnector

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.

• Analog 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 TüNTM Software Interface. Refer to the table below for detailed info and decide which option is best suited for your specific system.

Design Mode Function Connection
Remote	Conventional (Preferred)	Turn-en/off controlled by your source unit.
