There is so much more to power cables than just the gauge of the wire. Carlsbad, you are so far off, your reply was foolish. 1st, the owner needs to check with the component manufacturer to see what the minimum amp rating is required before any assumptions. 14ga for an amp but 10ga for a speaker? You don’t know what you are talking about. I know of amps that require 20 amp cables and 14ga isn’t going to work. I also know many speaker and subwoofer companies that use smaller than 10ga wire for their power cords. My cable to my power amp is rated for 30 amps.
There is much more to wire than just the gauge: copper/silver, multi strand/solid, shielded/not, sheathing used, and especially termination connectors.
After doing my own testing over 15 years ago, every component in my audio systems has an after market power cable. I have a few thousand dollars worth of a couple cables in a box (due to changing of equipment) just in case I buy a new audio component.
