Thanks - it is weird. But from a brief search it seems to be what they're doing on Spike 1 systems - perhaps for some fake surround sound effects (at the expense of coherency and bass output). More interesting is the fact that they're using red wires for negative. Pins 1 and 4 here are the left and right negative terminals! So I've reversed the wiring on my left speaker so both have red on the negative.
I need some nylon spacers to recess the new speakers so I can fit the grill back on lol, although they seem to fit aesthetically like this too
Edit - scratch that, I'm reading the plug upside down lol. Carry on!
