I think the speakers may be wired with coaxial cable, which is why it looks wrong. I think the screens are connected to the (-) terminals and the centre conductors to the (+). This is not the right sort of cable for speakers.

As for the bulbs, personally I would substitute LEDs for them, but that would need a bit of experimentation, depending on the voltage being fed to them.
