Overview
The RF-HLC4 is a 4-channel high-level to low-level signal converter designed for factory or aftermarket radios that do not have dedicated low-level RCA outputs. It converts speaker-line signals into low-level audio suitable for feeding a 4-channel amplifier.
Best for
- Vehicles with head units that lack RCA outputs and users who want to add a 4-channel amplifier to their system.
Key points
- 4-channel high-to-low signal converter
- Designed for radios without dedicated low-level RCA outputs
- Converts speaker-level outputs into low-level audio signals
- Enables connection of a 4-channel amplifier for higher output
Fit and use
The adapter is intended to tap speaker-level outputs from a factory or aftermarket radio and provide low-level outputs for a 4-channel amplifier. Verify that your radio has speaker-level outputs and that your amplifier accepts low-level inputs before purchasing.
What to know
Confirm your radio exposes speaker-level outputs; the RF-HLC4 is for systems without dedicated RCA jacks. Verify your amplifier accepts low-level (RCA) inputs and that channel counts match. This product converts signal levels; consult product resources or a professional if you need help confirming compatibility.
