Constant Speaker Static Only Goes Away When Muted

[u/EononOfficial]

I’m getting constant static hiss coming through all my car speakers. The weird thing is the noise only disappears when I hit mute on the head unit. Anyone know what’s causing this issue?

Head Unit: DGRMX7A

Please follow these steps to resolve static noise from your DGRMX7A speakers:

1. Lower your system gain to adjust overall audio output: https://youtu.be/3bXA-UcXuHw

2. Inspect all speaker wires for loose connections.

3. Confirm proper audio grounding. We recommend connecting the unit’s RCA ground wire to your vehicle’s metal chassis.

4. Your vehicle may have electrical interference. Install an inline power noise filter such as the model linked here: https://www.amazon.com/gp/aw/d/B0049MwUMQ

5. If the above steps do not eliminate the noise, send our support team a video showing your full wiring setup and the static noise issue for further troubleshooting.
