Wiring 5 outdoor in ground speakers to indoor receiver

look at the second link.

I do appreciate the link and interestingly, I had already watched it but still need some explanation. I am installing 6 in ground TIC GS3 speakers in my back yard. There is already 14/2 wire attached to the speakers and I want to wire these six speakers to two separate input wires. I received a diagram from TIC but have questions regarding the diagram, link below.

If I want to have the best sound outcome, is the series/parallel combination the right way to go and do you need to have an even number of speakers to accomplish this. Also I have a very short span of wire coming out of the speaker so I will need to splice a section to each speaker just to connect them together based on the diagram above. I guess I need someone to talk me through this if possible. Any help would be greatly appreciated.
