I need some basic and clear guidance as to how to wire up a new set of aftermarket rear speakers.

The plugs off the old speakers look like this and understand from other posts that i either need to get an adapter (but which one) or cut off the black plugs and solder the wires to the new speakers. But which wires do i connect to what, as i understand that one set of wires from each side is for the rear tweeter, which i don't really care whether they remain working or not?

Many Thanks. I noticed these but couldn't find a cross reference as being the right ones for the Octavia MK1 hatch, so wasn't 100% sure? Can you confirm that these are defo the right connectors or can someone else verify?

yh those are them

cool. Thanks very much.
