Jeep WJ Grand Cherokee How To Upgrade/Modify The Factory Sound System

Welcome to the JeepSpecs.com in-depth page on how to upgrade the WJ Generation Jeep Grand Cherokee sound system. We have organized as much information as we could find into a helpful table below. Is something incorrect or missing? Please get in touch with us and we’ll fix it!

 

— Under construction —

hris Henry’s 550-watt JL Audio® system upgrade included the Stealthbox subwoofer. The factory head unit was retained.
<One of the “mods” that many Grand Cherokee owners put near the top of their list is an upgrade of the factory sound system. Whether it be the standard system or the Infinity Gold system, dramatic improvements can be obtained, as with any vehicle, by upgrading some or all of the components. There are a lot of different options (and opinions) depending on what your ultimate goal or upgrade intention is, and of course your budget. Different radio head units, upgraded speakers, more powerful amplifiers, subwoofers and more. Research is essential and the more the better. Spend some time visiting (or participating in) web message boards such as the Stereo and Electronics forum at Jeeps Unlimited.com. Additional information can also be found on the mobile audio related web sites listed at the bottom of this web page. By studying different systems and installation techniques you’ll be amazed at what you will learn, not to mention saving yourself a lot of time, trouble and expense on your own installation.

The goal of the “Options” section below is to try and sort out the variations of possible upgrades to the WJ factory system and to define what is needed or recommended for the upgrade and installation. This section will be expanded in the months ahead to clarify and describe the many different options as best as possible.

# 1 Factory Replace Factory Factory

OEM-1 Interface and cables for adding a new amplifier

The easiest and least expensive upgrade is to simply replace the stock Infinity speakers. The stock Infinity speakers are well matched to the head unit and amplifier so changing out just the speakers does not result in a very noticeable sound improvement. However, many owners use this as a “first step” in their upgrade path, especially when budget is a consideration. A new amplifier and/or head unit as well as other components can be added in the future.

Components:

Dash: 2x 2.5″ tweeters (some brands of 3″ tweeters can be used but require custom fitting)
Front doors (Bass): 2x 6.5″ speakers (or 2x 6″x9″ speakers)
Rear doors (Full-range): 2x 6.5″ speakers

Accessories/connectors:

# 10 Aftermarket speaker to factory speaker harness. (door speakers only)
# 11 Speaker mounting templates (to install 6.5″ speakers in front 6×9 opening).
# 11 Speaker mounting templates (to install 6.5″ speakers in rear 6.5 opening. Some speakers will fit in the same space as the factory speakers but the adaptor plates make for a tighter and better fit).

# 2 Factory Replace Replace Factory

OEM-1 Interface and cables for adding a new amplifier
This option replaces/upgrades the factory Infinity amplier with a higher quality and more powerful version. When upgrading the amplifier it is also recommended to replace the factory Infinity speakers with high quality aftermarket speakers.

Installation option 2a: (using OEM-1 adaptor)

The OEM-1 has built-in signal level converters. One of the cables plugs into the OEM-1 and the factory radio, and the other is a short harness offering 4 channels of RCA output and the trigger feed for the amplifier. RCA wires and one remote wire will have to be run from the OEM-1 at the head unit back to the location of the new amplifier.

You will also need to tap into the factory speaker harness under the rear seat (6 speakers=12 wires) and run those to the amplifier speaker output terminals (or run entirely new wiring from the amp to all of the speakers). See “New amp to speakers connection” diagram below.

The new amplifier will need a power feed run directly to the battery. The ground wire for the amp can be attached to the vehicle body near the amplifier mounting location.

Although costing at least $100, this adaptor package makes installation a lot easier for owners upgrading their amp as it saves tapping into the 8 input wires (as in option 2b below) and has the signal level converters built in.

1999-2001 head units:
OEM-1 Interface + “ADD-CHR” and “AMP-RCA” cables.

1999-2004 head units:
OEM-1 Interface + “ADD-CHR2” and “AMP-RCA” cables.

Summary of parts needed for Option # 2a Installation:

1x 4-channel amplifier
2x 6.5″ front Door speakers (or 6″x9″)
2x 6.5″ rear door speakers
2x 2.5″ dash tweeters
1x OEM-1 Interface plus two cables
1x 20′ 4-gauge power cable with fuse (amplifier to battery)
1x Short ground cable (amplifier to chassis)
2x 20′ RCA wire pairs (From OEM-1 unit to amplifier)
6x Speaker wires, RCA on one end (amp), bare on other end (from amp to factory speaker harness under rear seat)

The OEM-1 kits are available from Tune-Town.com

Installation option 2b: (without using OEM-1 adaptor)

Installation of a replacement amplifier without using an OEM-1 adaptor requires tapping into both the 8 audio output and the 12 speaker wires in the Infinity harness at the existing Infinity amp location and adding signal level converters (as shown in the diagrams below). New wiring can also be run from the new amp to the speakers as some owners do for their installations, but this involves a lot of extra work and is not really necessary for most applications.

Summary of parts needed for Option # 2b Installation:

1x 4-channel amplifier
2x High to low signal level converters
1x 20′ 4-gauge power cable with fuse (amplifier to battery)
1x Short ground cable (amplifier to chassis)
6x Speaker wire pairs, RCA on one end (amp), bare on other end (from amp to factory speaker harness under rear seat)
4x 6′ RCA wire pairs (signal converters to new amplifier)

OEM-1 Interface and cables for adding a subwoofer amplifier

This installation is most easily accomplished with the OEM-1 and two cables. The OEM-1 has built-in signal level converters. One of the cables plugs into the OEM-1 and the factory radio, and the other is a short harness offering 4 channels of RCA output and the trigger feed for the amplifier. RCA wires and one remote wire will have to be run from the AOEM at the head unit back to the location of the new amplifier.

The new amplifier will also need a power feed run directly to the battery. The ground wire for the amp can be attached to the vehicle body near the amplifier mounting location. The subwoofer is wired directly to the new amplifier

Helpful or required accessories:

1999-2001 head units:
OEM-1 Interface + “ADD-CHR” and “AMP-RCA” cables.

5a. Replacing the factory head unit with a different or upgraded factory head unit:

Owners of WJ’s with just a basic AM/FM radio with cassette or CD player can easily upgrade to just about any other radio unit made for the Grand Cherokee’s. Installation is a 5-minute “plug and play” job. Two different connectors are used on the WJ’s, 1999-2001 models have a dual 7-pin connector while 2002-2004 models feature the new style 22-pin connector. If you are installing a newer radio in a 1999-2001 Grand Cherokee you will need the Mopar P/N 82207541AC harness adaptor kit, Accessory # 9. This kit includes the antenna adaptor.

5b. Replacing the factory head unit with the factory RB1 Navigation radio:

The RB1 will plug right in to any 2002-2004 WJ and fit perfectly into the dash with no modifications. With the harness adaptor kit mentioned above the unit can be installed just as easily into 1999-2001 vehicles. See the RB1 installation page for detailed information on installing the navigation radio.

5c. Replacing the factory head unit with an aftermarket head unit:

The easiest solution for this upgrade is to use one of the OEM-1 adaptor kits, as seen in the photo above. The OEM-1 has built-in signal level converters and no cutting or splicing of the factory wires is required, making the installation of an aftermarket deck extremely easy.

See Accessory # 6a for OEM-1 kit information and cable Part #’s.
Harness wiring adaptors for the WJ

Alternatively, and cheaper, “Plug and Play” and other conversion cables are made for most brands of car stereos. See Accessory #6b below for the cable choices for different brand head units and different model year WJ’s. Some cable adaptors have a plug on one end and bare wires on the other so that just about any brand aftermarket radio could be used. The plug fits into the factory radio harness and the bare wires are crimped or soldered to the new aftermarket decks wiring harness. A bezel trim kit is also required for any 1-DIN size aftermarket stereos to fit the 1.5 DIN oval dash opening used in all WJ’s.

Helpful or required accessories:

Accessory # 1. Antenna adaptors (starting with the 2002 model year Chrysler switched to a new style locking antenna connector. If you are upgrading to an aftermarket head unit you will need an adaptor. An adaptor is also required when installing a 2002-up factory head unit into a 1999-2001 WJ.)

Accessory # 2 CD changer cable (for connecting factory CD changer to factory radio)

Accessory # 3 CD changer cable/adaptor (for connecting aftermarket CD Changer to factory radio)

Accessory # 8. Radio bezel trim kits (required for installing most aftermarket decks.)

Accessory # 9. Radio harness adaptor kit (for installing a 2002-2004 factory radio into a 1999-2001 vehicle. The 2002-up radios feature a 22-pin connector vs the dual 7-pin connectors used from 1999-2001.)

6. Radio: Replacing or adding an aftermarket head unit

Back to Accessories index

Option 6a – OEM-1 Interface

The OEM-1 interface adaptor kit is used when replacing or adding an aftermarket head units such as Kenwood, Panasonic, Alpine, Pioneer, etc. to the Infinity factory sound system. The OEM-1 has an 18 pin connector on one end and a 16 pin connector on the other. Once the two cables are chosen for the particular installation, just plug them into the OEM-1, plug them into the factory radio harness and then plug into the aftermarket stereo that is being installed. No wire connections to the factory harness or ccnnectors are required. The factory cables are not cut or removed – they are used.

The model OEM-1 is a four channel device that gives you 2:1 gain as well as infinite attenuation. This allows signal adjustment to the correct level between the factory system and what is being added or changed. All four channels are individually adjusted for accurate sound levels. Each channel completely isolates the aftermarket equipment from the factory system to give 100% compatibility in every installation. Correct phasing is maintained. Signal ground is also isolated to avoid ground loops.

Using the OEM-1 interface to add an aftermarket head unit requires the OEM-1 unit plus one “A” cable and one “B” cable:

c1. CHRY98/PC-POD

7c2. 2002-2004 models (compatible with RB1 navigation radio)

P.I.E. model CHRY02/PC-POD. The only iPODŽ interface that allows DIRECT PLAYLIST ACCESS, as well as track up/down, fast-forward, rewind, and shuffle functions to be controlled from your factory radio.

This interface also allows ‘fast track’ which is a rapid track up / down function, and ‘bank select’ which will allow you to select banks of 99 songs, for more rapid navigation through your iPod music collection. This device will also charge your iPOD while it is connected to your vehicle.

With this single interface, you can listen to, charge, and control your Apple iPod (3G, 4G, and Mini) through the CD changer controls of your OEM radio. Simply plug the i-Pod into the provided dock cable, stow your iPod out of sight, and enjoy your iPod music library. Control of the I-Pod interface is now accomplished through the CD changer/steering wheel controls of your OEM radio eliminating the need to fumble with the iPod while driving. Simply configure your favorite iPod music into 6 or 10 identifiable playlists (number of playlists depends on the OEM radio). You can then select these playlists using the disc select functions of your OEM radio. Each playlist is seen as a disc to the OEM radio and has the capacity to hold up to 9,999 songs!

9. Radio: Harness adaptor for installing a 2002-2004 radio into a 1999-2001 vehicle

Factory head unit from 2002-2004 installed into earlier 1999-2001 models. This wiring harness adapter is needed when installing a factory radio equipped with the newer 22-way connector into a vehicle equipped with the older style 7-way connectors. For the 2002 model year, Chrysler changed most of their radios over to a new 22-pin connector set-up. Some base WJ models for 2002 still featured the older style 7-pin connector. The harness kit from Mopar also includes an antenna adaptor to convert the new style antenna plug in the radio to the standard vehicle antenna cable used in 1999-2001 models. Mopar P/N 82207541AC.

This adaptor harness was designed to allow 2002 radios with the 22-way connector to fit in same model year vehicles with the 7-way connectors. Mopar does not recommend installing 2002-up radios in 1999-2001 WJ’s if you are keeping the factory speakers and amp system. Due to preprogrammed audio equalization levels that are in the vehicle’s body controller, if a signal from the radio is not recognized by the body controller, the unit will default to a flat curve. Combined with various levels of speakers used from model year to model year, the sound quality of the audio may be reduced. However, some 1999 and 2000 WJ owners have installed the newer radios (and RB1 Navigation unit) and reported positive results with the factory sound system.

Note: If the radio has CD changer controls, a special 10-pin to 8-pin cable can be purchased to allow the use of a factory changer.

11. Speakers: Mounting templates

Back to Accessories index

Templates for mounting 6.5″ round speakers into 6×9 factory front door openings (1999-2004 WJ). Several companies sell generic adaptor plates for fitting 6.5 inch speakers into a 6×9 openings. If you are planning to install a component set of speakers, some of these adaptors do not provide room for the separate tweeter and custom plates must be cut. Scosche now makes an injection molded adaptor that will allow for both the 6.5″ speaker and a component tweeter – P/N 142 SA69. They also make one for the rear 6.5″ speakers – P/N 142 SAC656. Even though aftermarket speakers will fit directly into the rear door holes, using the adaptor is easier and also a better fit for mounting the speaker. See Front door speaker installation and Rear door speaker installation.
