StealthMod™ Audio Upgrade for the 2007-Up BMW X5 with Premium "Harman/Kardon Logic 7 System"
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 our 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.
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.
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.
This StealthMod™ package contains:
1 ea. XD700/5 system amplifier
1 ea. Custom-engineered amplifier mounting bracket (steel)
1 ea. Replacement battery cover
1 ea. CL-SSI signal summing interface
1 pr. C5-075ct silk-dome component tweeters
1 pr. C5-525-XO passive crossover networks
1 pr. Custom-engineered crossover mounting brackets
1 ea. System wiring harness (includes power, speaker and signal wiring)
1 ea. HD-RLC remote subwoofer level control
Illustrated installation and setup instructions.
This StealthMod™ is designed to be paired with:
SB-B-X5E70/10W3v3 (94517) - Sold Separately
Please note: Much like a performance modification to an engine or suspension will invalidate portions of a vehicle's factory warranty, the installation of a StealthMod™ system will likely invalidate the factory warranty of the OEM audio system. JL Audio's warranties only cover the installed JL Audio equipment and do not extend to cover any failures of OEM (factory) equipment. While we have made every effort to create a reliable upgrade package, with great power comes great responsibility... meaning that the additional power offered by this upgrade can damage factory speaker systems if it is used in an abusive manner (driven into severe clipping, for example).
