Hi all I have an issue with the Canton system on my 2016 L&K Superb. The drivers side bass speaker is distorted. Thinking it was the speaker, I removed the door card and substituted for a new one, but the problem persisted. A search on the forum showed this to be a common problem, normally sorted by doing a reset, but this hasn’t cured mine! So, suspecting the amp, I took the cover of, but no matter what I tried, I could not release the main plug. It appears to have a handle to ratchet the connector in, but I can’t figure out how to release it. Here is a photo of it. I would appreciate any help given. Thanks in advance. Mick.
