"Hiss" Sound when Sound is off after SR+ Audio Upgrade

I upgraded my 2021 SR+ audio system to activate the 4 front tweeters and add a subwoofer.

I did the installation in January and everything was perfect since a few weeks ago.

When the audio is turn all the way down, the passenger side door and pillar tweeter produces a "hiss" or "white noise" sound. It's very low, but it's definitely present. This is only happening on the passenger side and in the afternoons. When I drive in the morning, it does not make that sound.

My system consist of activation plug with bass blockers, Focal ICU 200, Alpine KTP-445U, Rockford Fosgate Amp, and JL 8W3 w/ OEM enclosure. Everything was purchased brand new.

I would appreciate any help or things to look at that could cause this issue.

Thanks in advance!
