Premium Sound. Factory Functionality.
A properly integrated audio system should feel like it belongs in the vehicle. High Grade designs upgrades around compatible factory technology so you can improve audio performance without unnecessarily sacrificing the features you use every day.
Depending on the vehicle and system architecture, integration can preserve factory displays, steering-wheel controls, navigation prompts, vehicle alerts, cameras, source controls, and other OEM functions while adding the processing, amplification, and speakers needed for a higher level of performance.
