@millercarbon Do you think it would make a difference to a sub to go from the mfr supplied cord which is 10 gauge to a 14 gauge cord? If not, then this is going to be one inexpensive shopping experience (for once).

Well first of all if you have one try it and see. I doubt you will notice any difference. 

Here's why I say that. My Medusa power center is this Frankenstein monster that goes back a good 20+ years. Back then I played a lot of CD and had wired the thing with an isolation transformer for the CD outlet. CD doesn't need a lot of power so it was a 25W transformer. Silver wire. The wires going in and out of this are not much thicker than a hair. We had a word for this typically thick and curly sort of hair back in the day, pretty sure not supposed to use it any more. Pity. Would come in handy right now. Anyway point is all the power going to the CD outlet had to go through this 25W transformer with the, uh, hair thin wire.

Can you see where this is going? When the 2 Dayton sub amps were added: Oh there's an empty outlet let's use that one. And the bass was.... awesome. Absolutely awesome. Except, sometimes at the highest levels the lowest bass would clip. Rather obviously. Other than that, anything less than earth shattering levels everything seemed fine. 

Eventually I open the Medusa up to do something and discover to my horror I was running two thousand watt amps off one 25W transformer! 

Needless to say I re-wired and with the amps now plugged into an outlet with 14 ga wire there never is any clipping, ever, and the bass does have a little more slam. But nowhere near what you might think. In fact I would lay odds if I posted the question what will happen if two thousand watt amps are run through one 25W transformer with hair thin wire everyone would say, RU nuts its gonna explode! Burn out. Or worse. Anything but what actually happened, which was nothing.

Try what you have. Be careful with the advice you get around here. DYODD.

Thanks, all.

Unlike many purchases, I’m trying not to overthink this one.

Well first of all if you have one try it and see. I doubt you will notice any difference.

I agree, which is why (a) I’m not especially interested in doing comparisons and why (b) I only want to know what will work, mechanically.

It’s because I *don’t* have one that I’m asking the question.

As a P.S. I don't want to overspend because I'm convinced that multiple subs is the direction I'll go, and I may sell this sub and get two others that match. So this is just about the *now*.

Reality check. A 10 amp cord is 16 gauge, not 10 gauge. A 350 Watt amp like the REL has is going to pull maybe 3 amps. https://www.amazon.com/Cable-Leader-Universal-IEC320-Listed/dp/B07KBFF3RD/ref=sr_1_10?dchild=1&k...

The Volex 1625 power cord is rated for 10A but is 18AWG, NOT 10AWG. Same for my Rel sub and I replaced it with a 14AWG PC which is rated for 15A.
