o w n e r ’ s m a n u a l

Thank you for purchasing a JL Audio amplifier for your automotive sound system.

Your amplifier has been designed and manufactured to exacting standards in order to ensure years of musical enjoyment in your vehicle. For maximum performance and extended warranty coverage, we highly recommend that you have your new amplifier installed by an authorized JL Audio dealer. Your authorized dealer has the training, expertise and installation equipment to ensure optimum performance from this product. Should you decide to install the amplifier yourself, please take the time

to read this manual thoroughly so as to familiarize yourself with its installation requirements and setup procedures.

If you have any questions regarding the instructions in this manual or any aspect of your amplifier’s operation, please contact your authorized JL Audio dealer for assistance. If you need further assistance, please call the JL Audio Technical Support Department at (954) 443-1100during business hours (Eastern Time Zone).

PROTECTYOUR HEARING!

We value you as a long-termcustomer. 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 highpower 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.

INSTALLATION APPLICATIONS

This amplifier is designed for operation in vehicles with 12V, negative-groundelectrical 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.

PLANNINGYOUR 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:

Your JL Audio amplifier employs an advanced type of heat management, called RealSink™.This feature takes advantage of convection and radiation effects to remove heat from the amplifier circuitry. For optimum cooling performance, the vertical heat sinks located at the back of the amplifier 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-upand 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-coolingis not necessary, but you still need to follow some basic guidelines:

Amplifier mounted vertically with heat sink fins pointing up: Optimum

Amplifier mounted horizontally, right side up: Good

Amplifier mounted horizontally, but upside down: Fair (not recommended if there is less than 1 inch (2.5 cm) clearance above the amplifier heat sinks)

Amplifier mounted vertically with heat sink fins pointing laterally: Fair

Amplifier mounted vertically with heat sink fins pointing down: Poor (not recommended)

If mounting the amplifier under a seat, make sure there is at least 1 inch (2.5 cm) of space above the amplifier heat sink fins to permit proper cooling.

Safety Considerations:

Your amplifier needs to be installed in a dry, well-ventilatedenvironment 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 using the supplied screws so that it does not come loose in the event of a collision or a sudden jolt to the vehicle (20 lbs. of aluminum traveling at 60 MPH will hurt you).

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 500/5 is a five-channelsystem amplifier utilizing patented Absolute Symmetry™ Class AB technology for its front and rear channels and patented Class D technology for its subwoofer channel. Front and subwoofer channels benefit from JL Audio's exclusive R.I.P.S. power supply design which optimizes the output of each section for any impedance between 1.5 and 4 ohms per channel.

The staggered power distribution of the front and rear channel pairs (100W x 2 for front and 25 x 2 for rear) allows for a wide variety of application options.The 500/5 can be operated in the following modes:

1)As a full-systemamplifier inbi-ampmode with its subwoofer channel driving subwoofers in lowpass mode (250W x 1), front channels driving front component speakers (100W x 2) inhigh-passmode and rear channels driving rear component speakers inhigh-passmode (25W x 2).

2)As a full-systemamplifier in atri-amplifiedsystem, deliveringband-passedsignals through its front channels tomid-bass/mid-rangespeakers andhigh-passedsignals through its front channels to tweeters.

The 500/5's flexible input and crossover sections permit operation with a wide variety of source units and system configurations.The 500/5 can operate with a single pair of stereo inputs or with separate inputs for front and rear channel pairs, if the source unit is equipped with front and rear outputs.The subwoofer channel can be driven with a discrete signal from a source unit’s subwoofer output or can receive its signal from the front and/or rear channel inputs.

The 500/5's preamp output can send passthrough signals from the front inputs only, the subwoofer inputs only OR a sum of the front and rear input signals.This allows the connection of additional subwoofer amplifier(s) or full-rangeamplifiers.

TYPICAL INSTALLATION SEQUENCE

The following represents the sequence for a typical amplifier installation, using an aftermarket source unit. 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-connectionduring installation.

This step is not optional!

2)Run power wire (minimum 4 AWG) 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 2 AWG or 1/0 AWG power wire if additional amplifiers are being installed with the 500/5.

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 connected to the amplifier.

4)Run signal cables (RCA cables) and remote turn-onwire from the source unit to the amplifier mounting location.There are several ways to provide input to the 500/5. Please read the rest of this manual carefully to choose the best one for your system.

5)Run speaker wire 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 4 AWG power 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 using the

supplied screws.

8)Connect the positive and negative power wires to the amplifier. A fuse near the amplifier is not necessary.

9)Connect the remote turn-onwire

to the amplifier.

10)Connect the RCA input cables to the amplifier.

11)Connect the speaker wires 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 power wire fuse (50A for a

single 500/5) and reconnect the negative battery post terminal.

14)Turn on the source unit at a low level to double-checkthat 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 of the subwoofer channel and front and rear channel pairs to obtain the right overall output and the desired balance between their outputs. See Appendix B (page 22) 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.

To connect the power wires to the amplifier, first back out the set screw on the top of the amplifier, 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 receptacle on the front panel of the amplifier, 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 the same gauge wire as the power connection

(4 AWG) 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-metalconnection between the chassis and the termination of the ground wire.The use of a star washer to lock down the connection is advisable.

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.

that channel pair.This requires an RCA “Y-adaptor”(not included.) Connection of only one RCA input will result in reduced power output, increased distortion and can cause the amplifier to overheat.

Do not do this! Instead, use a “Y-adaptor”to split the mono signal into both left and right RCA inputs.

Why a mono signal? If you are bridging a pair of channels and use a stereo input, the only information that will reach the amplifier stage is the common-phaseportion of the signal.This may be useful for passively deriving acenter-channelsignal, but is not going to give you a defined left or right channel. If you are looking to reproduce a single channel’s signal, you must split the mono signal with a“Y-adaptor”and connect it to both left and right RCA inputs for the bridged channel pair.

STATUS INDICATOR LIGHTS /

PROTECTION CIRCUITRY

There are three status indicator lights on the top of the amplifier. These are as follows:

1)“Power” (Green): lights to indicate that the amplifier is turned on and operating normally.

2)“Thermal” (Red): lights to indicate that the amplifier has exceeded its safe operating temperature, putting the amplifier into a selfprotection mode, which reduces the power output of the amplifier. The red light will shut off and the amplifier will return to normal, full-poweroperating mode if the heat sink temperature drops back to a safe level.

3)“Low Ω” (Amber): lights to indicate that the impedance of the speaker load connected to the amplifier is lower than the optimum load impedance range for the amplifier.When this light is on, a protection circuit engages and reduces the power output of the front or subwoofer channel, depending on which channel is experiencing the problem.The amber indicator will also light when a short-circuitis detected in the speaker wiring (this can be a short between the positive and negative speaker wires or between either speaker wire and the vehicle chassis).This can be used to diagnose ashort-circuitby only connecting one of the amplifier sections at a time (front, rear and subwoofer).

The amber LED will light when you connect the section that is experiencing the problem and turn the volume up.

There is only one condition that will shut

down an undamaged 500/5 completely…

If battery voltage drops below 10 volts, the entire amplifier will shut itself off.The green “Power” indicator on the top of the amplifier will turn off when this occurs.The amplifier will turn back on when voltage climbs back above 10 volts.This may happen in a rapid cycle when bass-heavyprogram material causes a weak charging system to dip below 10 volts momentarily. If this is happening in your system, have your charging system inspected to make sure it is working properly. A 0.5 or 1.0 Faradrapid-dischargecapacitor connected in parallel to the amplifier power connections will minimize these short duration voltage dips in most systems that are having this problem.

For information on troubleshooting this amplifier, refer to Appendix D (page 26).

SERVICINGYOUR JL AUDIO AMPLIFIER

If your amplifier fails or malfunctions, please return it to your authorized JL Audio dealer so that it may be sent in to JL Audio for service.

There are no user serviceable parts or fuses inside the amplifier.The unique nature of the circuitry in the JL Audio amplifiers requires specifically trained service personnel. Do not attempt to service the amplifier yourself or through unauthorized repair facilities.This will not only void the warranty, but may result in the creation of more problems within the amplifier.

If you have any questions about the installation or setup of the amplifier not covered in

SYSTEM CONFIGURATIONS

STEREO BI-AMPMODE:

This is the most common application for a 5-channelamplifier. In this mode, the front satellite speakers, rear satellite speakers and subwoofer(s) are independently powered and filtered. Front and rear channels each have independenthigh-passfilters and the subwoofer channel has an independentlow-passfilter. Left and right front satellite channels deliver 100W x 2 @ 1.5 - 4Ω per channel. Left and right rear satellite channels deliver 25W x 2 @ 3 - 4Ω per channel. One mono subwoofer channel delivers 250W x 1 @ 1.5 - 4Ω.

Input Connection Options for the Stereo Bi-Ampmode are as follows:

A)Single pair of inputs connected to the rear inputs of the 500/5. In this mode, the user has no fading capability between the front and rear channels and no separate adjustability of subwoofer level from the front of the vehicle. See diagram A below.

B)Two pairs of inputs connected to the front and rear inputs of the 500/5 (a source unit or processor with front and rear pairs of outputs is required). In this mode, the user has front-to-rearfading capability withnon-fadingsub-basslevel.This means that the relative level of the front and rear satellites

can be controlled with the source unit fader, without affecting the level of the subwoofer channel. See diagram B below.

Note: This configuration can also be set up so that the subwoofer level tracks with the front channel level.To configure the system in this manner, go to the “Subwoofer Channel Control Section” / “Input From” selector switch and select “Front” instead of “F+R”.

C) Two pairs of inputs connected to the rear and subwoofer inputs of the 500/5 (a source unit or processor with front and rear outputs is required). In this mode, the source unit or

processor fader adjusts the relative level of the subwoofer channel vs. all four satellite channels as a whole.The relative level of the front and rear channels is pre-setwith the amplifier input sensitivity controls and cannot be adjusted from the source unit. See diagram C on page 16.

D) Three pairs of inputs connected to the rear, front and subwoofer inputs of the 500/5.This mode is applicable for use in systems with a source unit or processor that provides discrete front, rear and subwoofer outputs. In this mode, the subwoofer level and front to rear fading can be controlled from the front of the vehicle. See diagram D on page 16.

! IMPORTANT

Some source units and processors with subwoofer preamp outputs provide low-passfiltering on these outputs, while others have a fullrange output. Consult your source unit or processor owner's manual to determine the properties of the subwoofer preamp output.

If your sub preamp output is full-range,engage the 500/5's sublow-passfilter by selecting the

“12dB” or “24dB” position on the “Sub LP Filter” switch.This configuration is illustrated in the setup diagram.

If your sub preamp output has a choice between full-rangeandlow-passmodes, select the fullrange mode and use the 500/5's (likely more sophisticated) sublow-passfilter by selecting the

“12dB” or “24dB” position on the “Sub LP Filter” switch. This configuration is illustrated in the setup diagram.

If the source unit/processor sub preamp output has a low-passfilter which is not defeatable, you can turn the 500/5'slow-passfilter off by going to the “Subwoofer Channel Control Section” /

“Sub LP Filter” switch and selecting the “Off”

position. Depending on the crossover point and slope of the source unit/processor's filter, you may wish to engage the 500/5's sub low-passfilter tofine-tunethesub-bassresponse.

If you are using a high-qualityoutboard active crossover, you can defeat all of the 500/5's filters by selecting the “Off” position on the “Sub LP Filter” switch in the “Subwoofer Channel Control Section”, the“High-PassFilter” switch in the Rear Filter Section and the “Filter Mode” switch in the Front Filter Section.

L-RAmbience Control:

This switch, located in the “Rear Filter Section”, performs a very useful function when operating the amplifier in bi-ampmode. By switching this circuit to the “On” position, all signal common to both left and right channels is removed from the signal feeding the rear channels of the 500/5.When the circuit is “On”, the rear channels will only reproduce the extreme left and right information in the recording, creating a realistic ambient effect from the rear channels without detracting from the imaging of the front speaker system. Experiment with this switch to determine if this feature enhances the sound of your system.

D)Three pairs of inputs connected to the rear, front and subwoofer inputs of the 500/5.This mode is applicable for use in systems with a source unit or processor that provides discrete front, rear and subwoofer outputs. In this mode, the subwoofer level and front to rear fading can be controlled from the front of the vehicle.

STEREO TRI-AMPMODE:

In this mode, the bandpass feature on the front channels is activated, configuring the 500/5's crossover sections to true three-wayoperation. This allows the independent powering of tweeters, midwoofers and subwoofer(s) in the system and gives extensive control over level matching and crossover parameters. Left and right tweeter channels (25W x 2 @ 3 - 4Ω per channel), highpass filtered. Left and right midwoofer channels (100W x 2 @ 1.5 - 4Ω per channel), bandpass filtered. One mono subwoofer channel (250W x 1 @ 1.5 - 4Ω),low-passfiltered.

Input connection options for the Tri-ampStereo mode are as follows:

A)Single pair of inputs connected to the rear inputs of the 500/5. In this mode, the user has no adjustability of subwoofer level from the front of the vehicle. See diagram A below.

B)Two pairs of inputs connected to the rear and subwoofer inputs of the 500/5 (a source unit or processor with front and rear pairs of outputs is required). In this mode, the user has the ability to fade or control the level of the subwoofer channel relative to the mid and high-frequencychannels. See diagram B below.

L-RAmbience Control:

This switch, located in the “Rear Filter Section”, should be set to the “Off” position when operating the amplifier in Tri-AmpMode.
