Our take on the JL Audio StealthMod™ Audio Upgrade

by Buck Pomerantz
JL Audio

Turn that frown into a smile

The premium sound system in your BMW X5 doesn't sound as good as you thought it would, does it? JL Audio comes to the rescue with this StealthMod audio upgrade system that'll make you very happy with the sound in your ride. This package allows you to clear out the factory crossover setting, replace the tweeters, and increase the overall power, bringing excitement, impact, and a new clarity to your music. Adding the optional Stealthbox® subwoofer to this StealthMod system will complete your BMW's system upgrade and bring you the ultimate in customized sound.

C5075-CT tweeters

New tweeters and crossovers

C5-525 Crossover

In order to guarantee superior high-frequency reproduction in your BMW, the factory tweeters are replaced with JL Audio's C5-075ct silk dome component tweeters and C5 crossover networks. This change will bring out all the intricacies in your music, as well as set up a clearly defined soundstage that will make it seem as if the band is playing directly in front of you. The package includes tweeter mounting brackets that help simplify the installation.

One amp takes care of the whole system

XD700/5 amplifier

JL Audio's XD700/5 5-channel amplifier provides power for the entire system. This compact beast installs neatly out of the way, feeding your four factory speakers and your new tweeters up to 75 watts RMS each, while its sub channel will deliver 300 watts RMS to a Stealthbox, when you install it. This power allows all your speakers to operate at peak efficiency and eliminates distortion, so you enjoy clean sound, even at high levels.

CleanSweep Signal Summing Interface

Signal summing module ties the new system to the factory system

The JL Audio CL-SSI combines the high- and low-frequency outputs from the premium factory system, and presents a full-range stereo signal to the XD700/5 amplifier. The input sections of the Signal Summing Interface feature optimum level indicator LED's and trim pots for quick and accurate level matching that results in the cleanest and strongest signal possible. This little processor and the 5-channel amp mount on custom-fit brackets in the spot behind the left rear panel (where the factory amp lives) for a very neat installation.

Stealthbox for BMW X5

Optional Stealthbox sub

Add the Stealthbox subwoofer

Your upgrade really won't be complete without adding some bass to the system. This JL Audio Stealthbox subwoofer perfectly matches your BMW's acoustic space, and fits in without taking up much room. The Stealthbox contains one 10" W3v3 subwoofer, and it lives up to its name, as it broadcasts powerful bass throughout your X5 from beneath the cargo area floor.

Your own concert hall

Once the StealthMod installation is complete, you'll start thinking of your X5 as your own personal concert hall, as you experience the excitement that only a first-rate car audio system can create.

Installation Note: JL Audio has rated the difficulty of this StealthMod installation as high and recommends using a car audio professional to install this system, as this modification may void your factory radio's warranty. The package includes all the wires and hardware needed for a custom-fit, stealthy installation, along with photo-illustrated, detailed, step-by-step instructions.

Features

SMS-B-X5E70/L7 StealthMod: This particular StealthMod package has been designed for 2007-Up BMW X5 vehicles that are factory-equipped with the "Harman/Kardon Logic 7" premium audio upgrade package. This StealthMod system will not work in X5's equipped with the base audio system, nor will it work in X5's equipped with the 3rd row seating option. The StealthMod system has been thoroughly tested and engineered by JL Audio's research and design team and is designed to offer significantly greater clean output capability, better imaging and better-balanced high-frequency response than the factory system.

Note: This StealthMod is designed to be paired with the SB-B-X5E70/10W3v3 (94517); sold separately.

Components: A five-channel amplifier is included to power the front speaker system and filter its frequency ranges for increased performance. Two of the XD700/5's main channels drive the underseat factory woofers with a high-pass filter for increased power handling and reduced distortion and two channels drive the BMW door mid-range speakers and the C5 component tweeters that replace the factory tweeters in the A-pillar positions through a pair of C5 crossover networks. The amplifier's subwoofer channel begs for the addition of a subwoofer (sold separately) to complete the full audio spectrum. A CL-SSI is used as an active line-output converter in this system. The supplied HD-RLC Remote Level Control can be mounted in the front of the vehicle to be used as an easily accessible subwoofer level control.

Installation Notes: The XD700/5 amplifier installs below the OEM amplifier in the electronics compartment in the left-rear corner of the hatch. The CL-SSI installs above the factory amplifier in the electronics compartment located in the left-rear corner of the hatch. The C5 component tweeters replace the factory-installed tweeters located in the A-pillar. The C5 crossover networks install inside each front door.
