Hi all,

I have done a quick search of the forums, apologies if this has already been covered.

Anyway basically I was wondering whether anyone could give a detailed explanation of correct speaker wiring to make sure everything is in phase.

I have seen the coloured wire guide in the Brava Owners' site, but cannot find any indications on the actual speakers in the car of which are the positive and negative terminals (and I have already messed around with wire switching so cannot use an untouched speaker configuration as a template for the rest).

I have a 2001 Brava (with dashboard tweeters), cheers in advance for any advice.

Hummm could be interesting for me aswell i would like to know.

Stick a 9v battery across the 2 speaker wires...if the speaker cones moves outwards & the other 1 (or 3) do they are all in phase....if one goes in its out of phase with the others.(out of phase speakers sound dull as they cancel each another out)

T14086, many thanks for that, exactly the sort of practical solution I was looking for.

I also assume that if the positive and negative terminals on the battery are respectively lined up with Light Blue / Yellow and Light Blue / White wires going into Right-Hand Rear Speaker (see guide at http://www.bravo-guide.co.uk/ice.htm) and speaker cone goes out then that speaker is correctly wired; and similar process for rest.

Cheers again for the speedy response.

aslong as they all go in (or out) they are in phase with each another when doing battery test...its the AC signal from the head unit that will ultimely determine wether the speaker cone moves in or out

Its a DC current that moves the speakers and they do not like being reversed. They are designed to push air not pull, which is what happens if you wire them up back to front..

This might help you.........
