It converts amplified speaker signals from a factory or aftermarket radio into low-level RCA signals for an amplifier input. This makes it useful when the existing radio does not provide RCA preamp outputs.\u003c\/p\u003e\u003cp\u003eIt is intended for installers and vehicle owners who want to retain the original radio while adding an amplifier or subwoofer system. The two-channel format suits basic stereo-to-amplifier and subwoofer-amplifier signal integration. Its compact format is designed to fit into an aftermarket audio installation without requiring a replacement head unit.\u003c\/p\u003e\u003cp\u003eAn adjustable attenuation control allows the output signal level to be matched to the connected amplifier. Proper level matching helps an installer set up the system with an appropriate signal level before amplifier gain adjustment. The control is located on the converter housing for accessible setup during installation.\u003c\/p\u003e\u003cp\u003eThe GR-HL2 includes an integrated ground-loop isolator intended to reduce unwanted electrical noise in the audio signal path. It also provides a 12V remote turn-on output for an amplifier. This can simplify amplifier activation in installations where a suitable remote lead is not otherwise available.\u003c\/p\u003e\u003cp\u003eUse the GR-HL2 between the radio's speaker outputs and an amplifier's RCA inputs. It supports a straightforward upgrade path for adding amplified speakers or a subwoofer while maintaining the vehicle's existing radio and controls. A supplied wiring diagram provides connection guidance for the converter's integrated leads and RCA outputs.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Channel Signal Conversion:\u003c\/strong\u003e Converts left and right speaker-level signals to RCA line-level outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Attenuation:\u003c\/strong\u003e Lets the installer tailor converter output level for amplifier matching.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12V Remote Output:\u003c\/strong\u003e Provides a remote turn-on connection for a compatible amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround-Loop Isolation:\u003c\/strong\u003e Helps address electrical hum and noise in the signal path.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCA Line Outputs:\u003c\/strong\u003e Connects to an amplifier using standard left and right RCA inputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide Frequency Response:\u003c\/strong\u003e Covers a specified 10 Hz to 50 kHz range.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe GR-HL2 uses a compact black enclosure with integrated wire leads, left and right RCA output connections, and an accessible level control.
