Things to Know
• Active noise cancellation is an OE module that helps reduce unwanted background noise.
Microphones mounted throughout the vehicles are used to monitor sound levels and frequencies inside the vehicle's cabin. The factory ANC generates an inverted signal from the factory speakers to cancel out unwanted cabin noise. The ANC-CHH1 bypasses that factory system, allowing for the installation of aftermarket equipment.
- It is recommended that a polarity tester and tone generator be used before connecting your aftermarket equipment.
- Some vehicle require the addition of load resistors, there are multiple options available. We recommend AX-LR20, AX-LR39, and AX-LR60.
• Proper termination of loose wires is required.
