You shouldn't even have to do that; you could just get "stackable cables"...
that is, the plugs themselves should have a socket in the back of the plug
head into which you can plug another banana cable.  As far as I know, these
are more or less standard...

	Here's an ASCII rendering of what I mean...

I hope that made sense; also, I'm assuming your cables have male connectors
at both ends...or at least on the end that plugs into the supply.
