So, I've noticed recently that just about every wire company has bot OFC and CCA wire available, with OFC being the higher end line. My question is, In a car audio environment, where my power wire run will be no greater than 17 ft, is the difference in conductivity enough to make a noticeable (to me as an average consumer) difference? If not overdrawing or improperly fused? As an example: 4 awg run 60 amp fuse less than 12" from battery to amplifier that has a max current draw of 60 amps with a total length of the run being 12 ft? Amp ground at 18" on 4awg as well? Or say doing big 3 upgrade with 1/0 wire running above mentioned equipment/main power run to the back?
