Enhancing the sound system in your Audi A5 8T is a smart and rewarding project, especially if your vehicle came without a factory-installed premium system like Bang & Olufsen. Whether you're driving a Sportback, Coupé, or Cabriolet, this upgrade can significantly elevate your in-car listening experience without extensive modifications or high costs.
The solution presented here uses the Audison APK 165 2-way speaker kit, known for its excellent sensitivity and factory-fit compatibility. With minimal effort and no need for an external amplifier, you can achieve powerful, clean sound throughout your vehicle.
Why This Kit Works for Your Audi A5 8T
• Compatible with Audi A5 8T models built between 2007 and 2016
• Available for Sportback (5-door), Coupé (2-door), and Cabriolet (convertible) versions
• Front doors house 165 mm woofers and tweeters in the mirror triangle housing
• Rear speakers vary by model:
• Sportback – woofers mounted low and tweeters near the door handle
• Coupé and Cabriolet – both components are integrated in the side panels
• Designed only for vehicles without premium audio systems such as Bang & Olufsen
Superior Sound with MDF Mounting Rings
One of the standout features of this upgrade is the use of MDF (Medium Density Fiberboard) speaker rings in the front doors:
• MDF provides a dense, stable structure that minimizes vibration and resonance
• Improves bass clarity and midrange precision
• Treated to resist moisture and heat — ideal for long-term durability
• Factory-facing mounting holes are pre-drilled; speaker screw holes require drilling by the installer
