I have collected all the parts needed to re-install the system back into the wife's 53 plate MCS
One of the previous owners removed the lot, presumably down to a faulty amp and in the process cut off all the speaker connectors. They did install some quality speakers ,focal components to the front and JBL's in the rear, but I prefer oem
I have the full wiring diagram but I'm unsure of which are the + and - connections on the actual speakers.
If anyone can point me in the right direction I would be eternally grateful
