Re: Hitachi Car radio- Wm702R wire colour codes?
If it's just one speaker, and neither wire is connected to Earth, it won't make any difference which way around you connect it. If you use two speakers, they should be connected the same way around to prevent cancellation effects. (+ to + and - to -, in parallel; or - of one to + of the other and the remaining terminals to the set, in series.)

Makes perfect sense, thank you. I am testing it tomorrow so will hopefully hear just what remains on MW and LW these days.
