NEED BA REAR SPEAKER WIRES COLORS + - what are they please

LEFT ???? RIGHT ???? +- +-

Thanks in advance

Have you tried looking at the wires where they plug into the speaker itself??

They might be the same colour, the negative one having a black line/stripe on it, thats what most cars have..

But yeah cant help with the colour but thats how i figured out what mine were.
