2006 CLK-350
Intermittent speaker failure
This forum was very helpful in diagnosing a serious electrical problem with my husband's 2006 CLK-350. Let's see if our luck will hold with a long-standing but minor mysterious electrical problem.
He has had the car since 2009. I can't remember when this started happening, but it was in the first few years. 99% of the time the sound system works fine, but every now and then he will start the car to find there is no sound. There is power to the stereo, the buttons and station display are fine. This will last for an indeterminate amount of time, through several stop-start cycles, until suddenly he will start the car and there is sound again.
There is some kind of an electrical short associated with this failure, because we've found that if we leave the car sitting for long enough while it is in "no sound" mode the battery will drain.
Any ideas? He doesn't want to have it investigated unless he can take it to the dealership while the problem is happening and so far it has never happened at a convenient time. Besides, they could easily start it and find nothing wrong. But if we had a good idea of where to direct them to look it might not be quite such a money pit to get it fixed.
Thanks in advance!

Just to make sure I understand - are you talking about pulling and re-seating them while the problem is happening, to see if that fixes it? Or replacing them with new ones? Thanks!

I'll say this, when I pull a fuse, I personally replace it with one that lights up when burnt out. They are a bit more expensive, but its super awesome in the dark when the fuse lights up and you just know which it is. No guessing, just fixing.

Apologies for the basic question, but how does one check an amp? Neither of us is what you might call mechanically inclined. We can handle the fuses.
Of course it will all have to wait until it happens again, otherwise everything will check out fine I imagine.

If you know someone who has a good, working one, you could swap and test it out...or check ebay and pick one up for about 100$. Make sure all the connections between the headunit and the amp are not problematic first...and disconnect power...see if that resets anything.
