Is there any way of identifying which wire is which, going to the speakers in a MY03?
One wire is red and the other is grey...
Any suggestions?

put your tongue on them 
(disclaimer - not responsible for occuring shock)
Seriously though, is there not a small + and - symbol anywhere on the speaker near the contact plugs?

Get a small battery, like the little 12v ones used in alarm remotes, but the speaker wires on the terminals, if the speaker pushes out you have + & - the right way, if it pulls in then they go the other way around.

Sorry guys, I think you picked me up wrong.
I know which is which on the speakers (cos it says + & -)
I meant the wires going to the speaker from the factory loom.
One of these is red and one grey.
Which one do I attach to the + and which to the - ?

I assume you are changing the speakers and are planning to pull the head unit out. Really you are going to have to remove the head unit and do what I suggested in the previous post. Or you could just connect it up any old way play some music, if you balance to one side and find you have more bass than centred balance then one of them is wrong, so swap one and try again.

wannab4,
I'm familiar with the process you describe above, but the only purpose it serves is to identify which terminal is +ve and which is -ve on a speaker.
I was wondering if there were any ways of identifying which wire in the loom was which, other than simply wiring it up and seeing if it sounds right.....

A multimeter won't work - speaker signals are ac
1. Identify which terminals are positive / negative on the speaker.
2. Look at the connector and see which wire goes to the known positive terminal on the speaker...
Bingo! It ain't rocket science

Chiark,
The standard multiplug doesn't have +ve and -ve signs on it so you cannot tell which wire is which at the factory speaker end.
I eventually whipped the headunit out and identified which wire was which from there and traced each colour back to each individual speaker....
Just thought there may have been an easier way......
As it turns out, my guess was incorrect as I had both front speakers wired up incorrectly...... Didn't hear a noticeable difference though???
Cheers anyway

Cheers Jocky but I had already did as I described in my post above.
Gonnasuk.... I was querying which wire was which on the loom.... not the speaker.

The plug on the speaker only goes on 1 way doesn't it? If I'm wrong on that, then ignore the rest.
Work out which terminal is positive on the speaker. Then look to see which lug goes into it. Then note the colour of the wire. That's the positive one
Sorry if I'm missing the point here...

Chiark,
The speaker terminals on the factory 30W babies aren't marked with +ve and -ve so you'd still have to identify which was which at the speaker end.
I found it just as easy to identify them at the ISO connector end and note the wire colours.
