Negative and positive

[andybi78]

I took out the original speakers only to find one pink wire and one yellowy colour wire with no labels, can any one tell me which is positive and which is negative as i am finding it hard to tell.

if i remember correctly the pink is the positive.

oh, thats what it was in the rt, just realised you have a 172 never messed with the wires in one of those.

If you know which of the cables connected to which terminal on the speaker then you can find out, though surely if this was the case the speaker would be labelled?

Take 2 runs of cable and attach them to the speaker terminals (one to each), then take a 9V battery (the square one) and touch the two cables to the battery terminals, the speaker will pop, and if it pops "out" then the positive battery terminal is connected to the positive speaker, if it pops "in" then it is the wrong way round...dunnoif thatll help you.

Otherwise check out a Haynes Manual.

Take a look at the connection-points on the speakers themselves. On my 172mk2 + and - were indicated on them.

Are your changing your head unit too, if so you want to change the speaker cables for some decent stuff plus this way you can leave the original wiring alone for when you refit the old head unit

As nowhereman says look very carefuly at the connection on the speaker mine were marked.
