Copying this over from the 2.0 thread.
"So yeah I saw that about xlr power.
That's why I haven't whipped out my soldering iron out yet!
I have the connectors laying around from audio use.
I would like to use those old-school connectors for electric fry pans etc.
But they're obsolete for a reason I would imagine.
So sub 2.0 is transformed to 24(?)v dc to the heads (I think max is 48v?),
while sub 1.0 is 115v ac all the way through."
So I guess for my modular plan I will postpone box assembly for now and just concentrate on polarized plug connectors. I will probably make gfi box receptacles for female, one for my box and maybe one for the original sub controller box (but I would still have to hit it with my ball-pin hammer every time I turn it on because it buzzes quite loudly, which is the impetus for this project).
My plan here is to splice the Apollo's wire with a longer lead that has a plug at the end of it.
The important thing here will be to make an excellent soldered connection that is double-adhesive heat-shrink protected like the stuff on the Apollo itself.
So instead of finishing my box for now,
I will start with the "easy" button that was suggested earlier:
