I heard the lower the impendance is best for subs. Any thoughts on this since its rated at 22 pF per foot capacitance which is better than many?

I purchased mine to run from my S/PDIF output from my smart TV to my sound system, and I am unsure if this is best for a sub woofer, but I do know it is a high quality cable, and should suffice for your needs, especially for the price.

Can this be used in wall installation?

CL2 or CL3 means it's plenum rated or suitable for in wall installation. I purchased this cable for that purpose specifically.

Does this cable work well for a cd player with digital coax output to amp input?

Yes. This is a digital coax. It looks like RCA plugs, only the wire is thicker, shielded RG6 and transports data digitally. Digital data like your cd player audio to your amplifier. Regular RCA cables are for analog data, like your game consoles video into your tv. In which case you don't really need the thicker cable and shielding. This should work perfect for what you are doing.

I suppose there are just right for connecting analog audio from a preamp to home theater amp?

They are RG-6 Cable which is capable of much higher frequency levels than Audio. So yes these are very good for analog audio connections.
