My W124 E320 does not output any sound from the radio, or tape player. I searched around in the trunk and found these two amplifiers on the right side with part numbers 124 820 1789 on it. I opened them up and did not find any fuses inside that could be replaced.



Searching on the left side, I find 2 plugs dangling around. Am I missing something here?



If not, where is this amplifier fuse located? Or is there something else I should look at to get the sound working?

Decided to change every single fuse in the fuse compartment in front of driver side. Eventually got to fuse C and replacing that allowed radio to work again. Fuse looked fine, but I guess was broken.
