extreme cold weather and speaker bass problem?

Morning guys -

East coast has been hit with some arctic temps this week, was single digits this morning when I get into my 2009 c63 amg. As my CD player turned on I immediately noticed a lack of bass in a familiar song. I checked a few more songs and yes, sure enough, there was no bass response from the Harmon Kardon system. My initial thought was, well, I guess the woofers are broken/fuse blown? I adjusted the bass levels all the way up and down and no difference in bass output.

Then I drove about 15 minutes to work and fiddled again, this time noticing some slight bass improvement and change when I adjusted the bass level...

So given that the car had warmed up some in the short drive I am now wondering...can extreme cold weather affect the speaker performance/woofers/bass output in the w204 C class? I've never experienced this type of issue in any other vehicle I've owned.

I'm looking for feedback here before I go to the dealer and claim 'something is broken'...

Would appreciate any thoughts -

Victor

From what I've read yes, cold weather can affect speaker performance.

Never happens to my C63. But it sometimes happens to my 09 BMW X5. It gets back to normal when the car gets warm up inside.

It's been down in the low, low 60's out here and I don't notice any change in bass response.

I believe there's a thermal circuit in the HK system to prevent damage.
