Hello CL. So lately I've been having this issue with my mark Levinson sound system. AM, FM, AUX, and CD channels works well, but my problem is that I'm not getting bass from the speakers. Also I feel like the general volume is lower that'll before. I remember before I was experiencing this issue at random but since some months ago, the problem is permanent.

​​​​​Could it be that my amp is acting wrong?

Thanks!

 

Hi 3sm1l, Most likely it's the subwoofer in the back that's faulty. You can try and fix the one you have or simply replace it. Part number is 86160-0WD80 or replace with shallow aftermarket 200mm one. Also, if you're interested, I have a repaired one that I can send (PM me)
