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.

2 | JL Audio - XD700/5 Owner’s Manual

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 considerations that you must take into account when planning your installation.

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.

Mounting the amplifier upside down is strongly discouraged. 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.

Safety Considerations:

Your amplifier needs to be installed in a dry, well-ventilated environment and in a manner which does not interfere with your vehicle’s safety equipment (air bags, seat belt systems, ABS brake systems, etc.). You should also take the time to securely mount the amplifier so that it does not come loose in the event of a collision or a sudden jolt to the vehicle.

Stupid Mistakes to Avoid

Check before drilling any holes in your vehicle to make sure that you will not be drilling through a gas tank, brake line, wiring harness or other vital vehicle system.

Do not run system wiring outside or underneath the vehicle. This is an extremely dangerous practice which can result in severe damage to your vehicle and person.

Protect all system wires from sharp metal edges and wear by carefully routing them, tying them down and using grommets and loom where appropriate.

Do not mount the amplifier in the engine compartment, under the vehicle, on the roof or in any other area that will expose the amplifier circuitry to the elements.

PRODUCT DESCRIPTION

The JL Audio XD700/5 is a five-channel, system amplifier utilizing JL Audio NexD™ ultrahigh speed switching technology for its four main channels and NexD™ high-speed switching for its subwoofer channel. The NexD™ technologies deliver outstanding fidelity and efficiency.

The XD700/5 can be operated with a wide variety of source units and system configurations.

TYPICAL INSTALLATION SEQUENCE

The following represents the sequence for a typical amplifier installation, using an aftermarket source unit or OEM Interface processor (like the CleanSweep CL441dsp).

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 re-connection during installation. This step is not optional.

2) Run 4 AWG power wire from the battery location to the amplifier mounting location. Take care to route the wire in such a way that it will not be damaged and will not interfere with vehicle operation. Use 2 AWG or larger power wire and a power distribution block if additional amplifiers are being installed with the XD700/5.

3) Connect 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 hardware (use of the JL Audio ECS master ground lug, XB-MGLU is recommended). Use 4 AWG 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.

8) Connect the positive and negative power wires to the amplifier. A fuse near

the amplifier is not necessary if the XD700/5 is the only device being run from the fused main power wire. If the fused main power wire is shared by the XD700/5 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.

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(s) (60A for a single XD700/5) and reconnect the negative battery post terminal.

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 14) for the recommended input sensitivity setting method.

16)Enjoy the fruits of your labor with your favorite music.

POWER CONNECTIONS

Before installing the amplifier, disconnect the negative (ground) wire from the vehicle’s battery. This will prevent accidental damage to the system, the vehicle and your body during installation.

The XD700/5’s “+12 VDC” and “Ground” connections are designed to accept 4 AWG power wire. 4 AWG is the required wire size for this amplifier.

If you are installing the XD700/5 with other amplifiers and wish to use a single main power wire, use 2 AWG or 1/0 AWG main power wire (depending on the overall current demands of all the amplifiers in the system). This large power wire should terminate into a fused distribution block mounted as close to the amplifiers as possible (within 12 inches / 30cm of wire length). The fused output of the distribution block will connect to the XD700/5 with 4 AWG power wire. JL Audio ECS fused distribution blocks are recommended (XD-FDBU-2 and XD-FDBU-4)

Note: Smaller AWG numbers mean bigger wire and vice-versa (1/0 AWG is the largest, 2 AWG is smaller, then 4 AWG, then 8 AWG, etc.).

To connect the power wires to the amplifier, first back out the set screw on the top of the terminal block, using the supplied 2.5 mm hex wrench. Strip 1/2 inch (12 mm) of insulation from the end of each wire and insert the bare wire into the terminal block, seating it firmly so that no bare wire is exposed. While holding the wire in place, tighten the set screw firmly, taking care not to strip the head of the screw.

The ground connection should be made using 4 AWG wire and should be kept as short as possible, while accessing a solid piece of sheet metal in the vehicle. The surface of the sheet metal should be sanded at the contact point to create a clean, metal- to-metal connection between the chassis and the termination of the ground wire. For optimal grounding, we recommend the use of a JL Audio ECS master ground lug (XB-MGLU). Alternatively, a sheet metal screw or bolt can be used with a star washer.

Any wires run through metal barriers (such as firewalls), must be protected with a high quality rubber grommet to prevent damage to the insulation of the wire. Failure to do so may result in a dangerous short circuit.

Many vehicles employ small (10 AWG - 6 AWG) wire to ground the battery to the

vehicle chassis and to connect the alternator's positive connection to the battery. To prevent voltage drops, these wires should  be upgraded to 4 AWG when installing amplifier systems with main fuse ratings above 60A.

FUSE REQUIREMENTS

It is absolutely vital that the main power wire(s) to the amplifier(s) in the system be fused within 18 inches (45 cm) of the positive battery post connection. The fuse value at each power wire should be high enough for all of the equipment being run from that power wire. If only the XD700/5 is being run from that power wire, we recommend a 60A fuse be used.

If fusing the amplifier near its power connections (when more than one amp is being run from the main power wire), use a 60A fuse. MAXI™ plastic-body fuses are recommended.

TURN-ON LEAD

The XD700/5 uses a conventional +12V remote turn-on lead, typically controlled by the source unit's remote turn-on output. The amplifier will turn on when +12V is present at its “Remote” input and turn off when +12V is switched off. If a 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.

The XD700/5’s “Remote” turn-on connector is designed to accept 18 AWG – 12 AWG wire. To connect the remote turn-on wire to the amplifier, first back out the set screw on the top of the terminal block, using the supplied 2.5mm hex wrench. Strip 1/2 inch (12mm) of wire and insert the bare wire into the terminal block, seating it firmly so that no bare wire is exposed. While holding the wire in the terminal, tighten the set screw firmly, taking care not to strip the head of the screw and making sure that the wire (not the insulation) is firmly gripped by the wire clamp in the terminal.

INPUT SECTION

The XD700/5’s input section allows you to send signals to the amplifier section through the use of two, four or six differential-balanced inputs.

Input connections are via up to three pairs of traditional RCA-type jacks.

If you wish to send six discrete channels into the XD700/5, simply use all six inputs and set the “Input Mode” switch in the “6 Ch.” position. The amplifier will automatically combine the Sub Ch. input signals to mono.

If you prefer to use only four channels of input into the XD700/5, set the “Input Mode” switch in the “4 Ch.” position and use the Ch 1 & 2 and Ch 3 & 4 Inputs. In this mode, the XD700/5 will derive its subwoofer channel signal from a sum of all four input signals. The bass will not fade when the signal is faded by the head unit from front to rear.

You may also choose to apply only two channels of input to deliver signal to all five amplifier channels. To do this, set the “Input Mode” switch to “2 Ch.” and use only the inputs to channels 1 & 2. In this mode, Channel 3 will operate with the Channel 1 signal and Channel 4 will operate with the Channel 2 signal. The amplifier will automatically combine the main

input signals to mono for the Subwoofer Channel.
