Can Interconnects be converted to speaker cables

Can interconnects be converted to speaker cables and does someone offer a cable end connector for this purpose? I'm sure it can be done.
I would not advise doing this. Speaker cables require a much larger gauge conductor than is typically used in an interconnect cable.
Why would you want to do this?

Alexs is correct. Speaker cables typically carry at least 1000X as much current as a interconnect. Re purposing interconnects to speaker cables would be inadvisable in almost all cases.

Don't know why you'd want to. You'd be chewing up a perfectly good pair of interconnects in order to convert them to speaker cables. And besides, its really not quite the same. If you want to try it, then by all means do it. But there's a reason ICs are ICs and speaker cables are speakers cables.
I agree with Alexs. Most (not all) interconnects are typically less than 20 gauge. Interconnects run a very low voltage and current where speakers require a LOT more current. That is why you would want a heavier gauge for the speakers.
no no and no don't even think about it
the impedance characteristics alone make this an exercise in futility
Morrow Audio cables, at least the early ones (I don't know about current versions), used the same thin solid core wire for both ICs and speaker cables, just a few more strands for the speaker cables. I'm still using them in both roles and like them a lot. Many speaker cable users employ quite thin wires very successfully.

Yes that is true but usually many wires. My Nordost frey speaker cables use 28 24 gauge wires where the ics use 6 26 gauge wires. Capacitance and inductance is quite different too.
Yes it can be done, but is will sound terrible. Each strand or wire should match and that is not the way IC's are made.
But in honesty the signal can be sent across most conductive material. You have only to lose and nothing to gain.
The 47 Labs OTA cable kit uses 26 gauge solid core copper wire, one for the positive and one for the negative. I never encountered a problem with these cables.

I think it just may come down to the IC you want to convert. However, it can be done and successfully.
I've been on both sides of this one. As to the thin wires I can assure you it does not sound terrible. Far from it. Back when Listener magazine was alive I read the late Harvey Rosenberg's treatise on thin solid core cables, using Radio Shack magnet wire, and gave it a try between speakers and amps at a time when I was using biwired Kimber 8TC between my SET amps and ProAc Response 3 speakers. Two single strands of 28 gauge magnet wire sounded a hell of a lot better as speaker cables than the Kimber, at that time, in my system, to my ears, though I was not alone.

Since then I've tried thin ribbon cable (Omega Mikro) and everything up to 14 gauge stranded. As noted, I'm back to the thin solid core Morrow Audio IC/speaker wires.

As Clio notes, it can be done and successfully. Try it and see.
MIT makes a product that will do what you want.Give them a call. I think they call it onewire.
If you are adapting to binding posts or banana jacks that have standard 3/4 inch spacing, you can use these adapters, costing $16.60 each:

The manufacturer's data sheet can be found here:

As several people have stated, though, gauge is a major concern. If the center conductor of your interconnect is in the area of 26 or 28 gauge, which is the case for many interconnects, a 10 foot run will have a resistance in the vicinity of 0.5 ohms. That will reduce whatever your amplifier's damping factor is to something less than 16.

If your speakers do not have low impedance at any frequencies, especially in the bass region, and if they do not require a lot of power, and if their woofers do not require tight control by the amplifier, and if the run length is not long, you MIGHT get reasonable results with that kind of gauge.
