When someone appraoches me wanting to help "tune a radio to an amp" (Oh No! - Mr. Bill) I use more of the lesser amount of Cap than most would. Only reason for that is the level of Carrier "strength" to Audio - as said earlier the Bass tones - or any strong envelope of audio (screaming or otherwise) tends to "bunch up" and pinch the signal being heard making it sound fuzzy muddy or (insert favorite potty-bowl commentary here movement) - worse (ahemn) on the receiver side.

I try to avoid that, I simply use the resistor needed to make the amp "hold" and then place a cap value of between 22uF to as much as 68uF (Bizarre values yes, but they do work ) depending on if the user wants to stay out of the neighborhoods' stuff and their Associations (think:HOA) newsletter as a topic of discussion(s).

Think of the Resistor as the means to set carrier, the caps' value to set swing using it.

IF you have the overhead (Wattage headroom more than 4:1) - you can use 100uF - but to go as high as 220uF - you may need to find more friends - for the ones that pause to hear a radio that needs to be Midas-ized - don't pause long and will keep searching for intelligent life on the band.

Best to start conservatively and use small uF Cap values to start with, for you don't know where the radio and your microphone with take your mouth.
