Hi everyone, new here! Got a 2013 SL 550 with Harman Kardon sound system. Bought it used, and I don't feel this sound system ever worked properly. Lately, bass/subwoofer work roughly half the time when I start the car. When weather is hot, or after I drove the car a bit, then stop - say at a gas station - and re-start, it may work, or stop working... It's driving me crazy! LOL! Any idea what it could be? Just a bad connection in the sound system wiring? Heard is all optic fibers, should I even touch this! Faulty amp? Is it easy to buy and replace an amp on that car? How could I diagnose what the problem is. A shop asked me for $13K to fix all that...! I laughed and left... MB dealer tried to sell me a new amp for $6K... All this is turning into a bad joke. Any help/idea/guidance welcome ;-)

Cheers,
Eric

How long have you had the car? Post some pics and overall experience so far. I have just purchased a '13 SL550 and waiting on delivery within the next week or so.

I forgot: bought my SL 550 3 years ago, low mileage. Besides the sound system that sucks, this car is AWESOME...! :-)

Do you have the 3D check box ticked? ... try unticking it

Hey David, I tried really hard, but I could not find that "3D" check box on my navigation... Where should it be? Cheers, Eric
