Metra 8112 Hiss (Aftermarket HU Wiring Harness)

[Rauhwelt]

Hello all,
I recently installed a new Headunit and am getting a hiss noise- via the RCA oem Amp integration on my new headunit. Do I need to use a RCA noise filter? Or is it a +12/grounding issue known with the LC100 chassis?

I used a noise filter (no dice )

Maybe its a snake But seriously, that can be annoying. Maybe some of your power or amp wiring is too close to the speaker wiring and your picking up the hiss that way. You could also try a different set of RCA cables. Some of them are made very cheaply and have know issues like hissing and crossover problems.

YotaMD has a video on a (long) fix for this.

I'm trying to figure out whether theres another way to circumvent it.
