rca audio cables (seymour road W4)

Hi everyone!

I'm hoping someone might be able to assist me with:

 a) Telling me which cables I specifically need to set this sound system up.
- 2 left/ 2 right / central pebble speakers and sub to connect to main unit.
- Do I need 6 x 1 RCA as per picture or 3 x 2 RCA?
- PHOTOS INCLUDED OF THE CABLE PORTS I'M WORKING WITH

B) Does anyone have any they might be willing to donate to the cause?

I can't travel too far but within w4 and local areas is no problem!

Thanks in advance! 🙂
