Please Read Before Purchasing
This package is designed specifically for the Audi A4 B9 AudiSound configuration and is primarily intended for professional installation.

The package is mostly Plug & Play in design, although minor modifications may still be required depending on the vehicle's exact year and trim.

Because this system includes multi-channel DSP amplification, professional calibration is strongly recommended. Correct DSP setup is important for crossover configuration, equalisation, time alignment, channel levels, phase and subwoofer integration.

Installation and DSP tuning fees are not included in the online product price.

Who This Package Is For
This package is designed for Audi A4 B9 owners with AudiSound who want a comprehensive speaker, subwoofer and DSP-amplifier upgrade rather than a basic speaker replacement.

• Better midbass performance
• Upgraded rear speaker performance
• Dedicated low-frequency reinforcement
• Increased system power

• Vehicle-specific integration
• A complete front, rear and bass upgrade

Installation & Tuning Notes

• Equalisation
• Crossover frequencies and slopes
• Time alignment
• Channel levels
• Input signal analysis and correction
• Phase relationships
