This brand new Mercedes-Benz SLS AMG received an upgrade utilizing Audison and Hertz Audio equipment over the pricey Bang & Olufsen factory upgrade which lacks overall impact. Although the B&O system equips the vehicle with more speakers to achieve it overall sound enhancement, the Audison and Hertz Audio system will utilize less speakers to achieve an audio nirvana within this sport coupe.
Retaining the factory COMAND multimedia system, an Audison Bit 1 processor utilizes the factory audio signal and manipulates it into a digital realm and reconstructs the signal removing unwanted audio effects and providing a true audiophile signal.
From the processor the signal travels to the Audison LRx 5.1K system amplifier. One of the best mobile audio amplifiers on the planet, the LRx5.1k provides 75 watts of class A biased for an extremely clean, linear, and distortion free sound to the Hertz Audio tweeters. A class AB design of the B channels of the Audison amplifier provide 250 watts of power to the midbass speakers, a Hertz Audio Mille 6 1/2" midbass. The fifth channel of the amplifier is the subwoofer channel, which supplies 1000 watts of power to the Hertz Hi-Energy 10" woofer located in a custom built fiberglass enclosure in the trunk.
The woofer enclosure was constructed in multiple parts and was reassembled in the trunk of the vehicle and fiber-glassed back together due to the tight space confinement. A half round cover was formed to provide protection to the cone of the woofer and also to tunnel the sound forward. A duplicate was formed for the opposite side to hide the Bit 1 processor and cables and keep the trunk symmetrical. The Audison amplifier was trimmed out and placed on the rear wall due to the high amount of heat generated from it.
The factory rear surround speakers, 2" were retained and powered off the factory COMAND radio system.
The system was completed with the implementation of an Escort 9500ci radar detector with front and rear laser jammers. The Escort system provides auto learning false alarm rejection along with a red light and speed trap notification database allowing the driver to enjoy the audio system on a drive no matter the speed.
