Audi A4 (B9) sedan with Audi sound system (ASS) | 6-channel DSP sound upgrade

Upgrade kits for the Audi A4 B9 with a factory-installed Audi Sound System (ASS). At its core is a 6-channel MATCH UP6DSP amplifier, which connects to the factory radio via a plug-and-play cable. The signals from the radio output are processed, optimized, amplified, and then sent to the speakers. The result is a significant improvement in sound performance; the sound system delivers remarkable dynamics, precise, powerful bass, and excellent, balanced sound. Included in the kit are the MATCH UP6 DSP amplifier, pre-loaded with the sound setup, the well-designed plug-and-play cable, and some installation accessories. We are also happy to install the upgrade kit for you. For consultation and appointment scheduling, please use info@ars-stuttgart.de
