In a perfect world you would be correct, but reality says, you wont be able to hear a difference, so it really doesn’t matter. Just use some decent sized cable, 12gage everywhere, I would recommend. Just to be sure, you could use 14. Or 16 gage, but for me, 12gage or 10gage, just for the extra head room. The smaller the gage the thicker the wire, so the less resistance the wire will have, so the easier it will be for the current to flow “though” your cables.. if your doing inwall wiring, get some bulk 12 gage cable and junction box, so you can have it terminated at the wall all nice and neat.. that’s what I did with my parents house. There are websites online that will tell you for what distance you are running the cable how much current that cable can handel usualy the farther the run the larger the cable you will need, due to the added length the cable will have a higher resistance to current…
Any other questions or what ever, ill be online for a while right now.
