The Audison APHASD is a BYPASS Plug&Play harness takes the ASD module inputs/iDrive outputs and bypasses them into the HiFi/ HK(674) OEM amp inputs. For the older MOST/digital HK OEM amp, the bypass harness prevents the ASD module from sending a signal into the system but keeps it powered and operating. (Active Sound is BMW’s designation for “artificial exhaust sounds”).
- NOTE: Not required or compatible with cars using AF BMW ReAMP3.

Why Choose Bankstown Sound for Your Car Audio & Tech Upgrades
At our Bankstown Sound store and workshop in Sydney, our team ensures every car and auto audio installation and upgrade starts with an understanding of how you use your car. Our team works with you to understand your driving habits, the features you rely on, and the problems you’re trying to solve.
Most factory setups are built to broad standards and often lack the clarity or seamless connectivity required for how people actually drive. That’s why we focus on modernising your dashboard and audio performance based on how you use your vehicle.
