Specifications

Multi-branched T-junction bypass loom designed to isolate primary analog inputs, line feeds, and vehicle digital databus streams. Extracts a flat, non-equalized, un-amplified full-range stereo signal directly from the factory head unit to route into the DSR1 processor. Relays bidirectional digital communications to maintain steering wheel controls, vehicle settings, warning chimes, fader control, and Bluetooth audio.

Key features

Plugs directly between the vehicle’s factory wiring harness and the DSR1 module, routing clean, un-equalized full-range audio inputs directly to your aftermarket gear. Integrates with the vehicle’s data networks to preserve original infotainment features, including steering wheel controls, vehicle settings, fader controls, tone adjustments, and Bluetooth communications. Specifically tailored to handle the unique digital impedance and communication hurdles found in vehicles equipped with premium, digitally-amplified factory sound systems
