Mark Levinson Audio System

[marksaitis]

Hi,

Problem with my mark levinson audio system:

1. I have started hearing cracking sounds from my rear sub-woofer when playing music with bass at around 37-40 few weeks ago. However, it used to disappear when volume got changed to 50 and over.

2. Half a week ago I noticed bass at the rear started to disappear completely for moments and come back, like multiple times over the period of few minutes. I just noticed that there is no bass at the rear today whatsoever.

3. Bass works fine on the front, but when I adjust the sound to play at the back only, there is no bass what so ever on any of the speakers on the rear doors and the rear panel - only the high frequency sound. I have tried playing music from AUX and from Radio - same result.

To summarise, bass now works fine in the front but there is none in any of the speakers at the read section of the car, I have closely listened to them all.

Any ideas?

Car is Lexus is220d with mark levinson and satnav year 2007

Kind regards,

Karolis
