Speaker Hissing (Static) solved

Shout out to Logic7 customer service and repair of my amplifier. The problem and symptoms I had were as follows.

2010 M3 which had a constant hissing coming over, I assumed the speakers. This started months ago as an interment static and over time turned into a full time static sound.

With Display off, static, with stereo on, static, bluetooth turned off, static. Car off static. After turning the car off at night I would enter the car the next day and it would still have a static sound without key.

I removed the optical cable from the amp and static stoped so I figured the amp was the issue.

I did some internet search and found solutions which assumed a blown speaker, replacing amp and installing a different brand or buying a new amp from BMW for $1900.

I found these guys at BMWLOGICSEVEN.COM and they were very good at responding to my emails and diagnosing and confirming that the amp was the issue. I sent the amp out and had it installed back in the car a week later. $350 well spent.
