Standard gauge splitter for speaker wire

Woud you use one of these to run 2 heads into one cab. Of course the heads would be used at seperate times, and with only one head on ata time. The purpose of the splitter is
1. So I do not have to reach back there for a cable switch each time; and
2. So I do not switch an amp head on without a load dump by accident.

My concern with the splitter connector is the meager gauge of the cable. However, it is a very short run

What say you all?

This not for speaker currents. Make something yourself - a box with jack sockets and a changeover switch. That way you leave both speakers plugged in and never have to worry about the amp running without a load.
 
Absolutely not!
If you cross the outputs of the 2 heads when one is on its output will also go
into the back end of the other, in essence giving the second amplifier an electrical enema.
I'm not an electrical engineer but common sense tells me this would not be a good thing.

:eek:
 
I'm curious why you need both on? I mean I get it if you need the wattage for playing the Albert Hall.........but........
---just curious---

Nope. No sir. Not me.
Guessing that’s a shield around a single(small) core.
Not for speaker loads.

TB-Don, I think the shielding is only for noise issues with regard to your guitar signal and does not hurt the amp. Below is an excerpt I found on the Fender website. You can see the full page here

An instrument cable (in cross section, above) is designed to handle low power and high impedance; a speaker cable (in cross section, below) is designed to handle high power and low impedance. The two should never be used interchangeably.

It is more about the stereo effect, not volume (I know it is just 2 mono signals, but still cool). It is also fun to try different combos on the fly, which is why I have that amp switching array on the floor. In this instance however, they would never intentionally be on at once since they share a cab. However, accidents happen. The Weber device above was designed for the performer who wanted to keep both heads on for a quick switch for different purposes. They also make a footswitch version for $156

That was my point sir.:D

Oh. I was just making the lesser point that shielding can't hurt the amp assuming everything else is proper, but I imagine that is not something you see anyway!

I have read that some amplifier manufacturers frown on the idea of shielded speaker cables...Mesa in particular. But that’s not what my first thought was.
My first thought was a high impedance cable, in a situation requiring low impedance, will lead to some deeply disappointing results. Then there’s the y cable used as a mixer concept...that doesn’t end well either with voltage involved.
