Oxidized connections (and cables) are insidious. I had very good cables before, but after quite a few years I changed (same grade, just new cables and connectors) and there was a certain "haziness" that disappeared. The change was motivated by length, not by sound. But once I heard the difference, I opened up a great length of my old cable and I could see a much higher level of oxydation than I would have anticipated.

The Emotiva site has this still posted... SUBWOOFERS: The Emotiva ERS-212 and ERS-112 subwoofer systems are in production, as well. The ERS-212 is a dual set, with two sealed 12 inch woofers and an external power amp. The ERS-112 is a single, sealed 12" woofer with an onboard amplifier.
Both the ERS-212 and ERS-112 feature and extensive menu that allow to tailor your low end like never before. The subs can be 'ready to go' right out of the box, custom programmed via an onscreen display, or by menu interface through your personal computer. Here's a small preview of the possibilities available with either the ERS-212 or ERS-112.
1. Multiple trigger inputs with 4 assignable options.
2. Multiple start up and shut down options.
3. Crossover can be selected in 1hz increments.
4. 3 selectable filter types: Linkweitz-Riley, Bessel, Butterworth
5. 6-24db per octave on the slope.
6. Full phase adjustment from 0-360 degrees.
7. Full alphanumeric display with programmable illumination.
8. 2 user defined EQs (full parametric).
9. Auto room correction

I stripped the 16 guage about 21 ft and noticed oxidation at 2 spots - this would explain the lack of clarity. The cable is now in the garbage!

I can understand how oxidization at the connections would have an effect on sound quality but I'm not understanding how surface oxidization on the rest of the run is affecting sound quality?

The oxidation in the rest of the wire is causing higher resistance to electron flow, the same as if the connection was corroded. The connection is usually the more susceptible area. This higher resistance now causes a sound difference.
This is the usual scenario when you hear people talking about how X cable improved their sound quality, it is simply a case of some extra resistance has somehow gotten into the previous wiring used.

I also wanted to add I do an annual cleaning of my equpment usually during the boxing week. During this time, I remove all the connections to my equipment and clean them up alcohol. Also the cables in question were used when I lived in a tropical place for ~4 years and I suspect it might have started the oxidation then.
