From my own experience I strongly suggest you consider removing all components and have them fixed. "If it ain't broken don't try to fix it" can become an expensive trap here.
As it was mentioned it's not a question IF your capacitors will leak, just WHEN. Leaking capacitors spill acid all around them which may cause a lot of damage to the circuit board or other components.

In my case there were bad capacitors in all 4 amps (on of them was so badly damaged that no repair was possible), the CDM box and the head unit.
Head unit was still working but already damage invisibly from the outside.

So... as a precaution I'd pull all those components and have them at least checked. It's more effort on the spot but bundles all components in one "downtime". And it mitigates futures risks.

Pulling the CDM is not as bad as it seems as you can work on it from the side (from below the fuse holder). It's still a PITA job but doable.

I know not everyone will agree to my all in one shot approach but personally I'd choose this approach for every upcoming C4 with bose that joins my garage.
