Hi,
Bought my brother some front door speakers for his mk3 GL...
Went to fit RH one Xmas day and not too obvious which of the 2 wires is + and which is -? Popped the other grill off and the wires are the same colour in other door?!
From memory:
Green with grey stripe
Blue with grey stripe
Without access to a multimeter does any one know which is which (+ or -)?
Thanks!

Blue is +. :)

He just emailed me to say he went with brown as positive, blue as negative (like in a house-hold plug). He's happy as they appear to work, whether they are firing the wrong way is another thing! :grin:
-
That's exactly what I thought and they work, but when I looked at the orignial connector and speakers, blue was +, swapped with wires and they sounded better.
-
the speaker wire with a brown tracer is the earth :)

Thanks peeps! I just emailed him to suggest he re-do them..... :grin:

Coming from a Audio Visual installation back-ground, I can tell you that the polarity of speaker wiring does not matter (unless its a 70v/100v line system, which car audio isn't)...with one important condition. Both (or all 4 speakers) are wired the same way. This is because you want all the speakers moving in the same direction at the same time...this is called in phase. Think of a speaker as an electric motor...or 2 motors in your case...you want them all "spinning" in the same direction. If you wire it out of phase, it wont damage anything...but you will notice a perceived loss of power (loss of bass to the untrained ear), this is because the sound waves produced by the 2 speakers are having to compete with each-other to move the air where as they would normally work as a team moving air in pulses at the same time.
