Cable for gigabyte ex58 rear speaker(s) out jack (black)

Hi,

I'm lost. Seems simple but I must be making it complicated or just not understanding something.

I have the Gigabtye EX58-UD2R board.

For speakers, I currently have Logitech 2.1 Z3000.

I now have two extra Logiech speakers with RCA cables.

The GA EX58 Read Speaker Out Jack (Black) is also RCA and the manual writes to, "Use this audio jack to connect rear speakers in a 4/5.1/7.1-channel audio configuration. Page 20-21 of my manual.

I find enough cables that have an RCA male plug end that splits out to two female plugs. My confusion being is that it is pretty evenly divided whether the two split out female ends have separate coloring, ie.: white and black and/or red and white such as:

or, http://compare.ebay.com/like/120701970632?var=lv&ltyp=A...*I7&GUID=ca9048d912e0a0e1e577c7f7ffff9738&itemid=120701970632&ff4=263602_309572


but, then another such category of cables have the same mechanical setup, i.e.: single RCA male to two split off RCA female plugs and appear to be designed for splitting a single signal into two parts for sending out, losing the ability to split off a left and right channel.

I believe by writing this out that the two examples with the URLinks above are what I need but, are they? Is there a differetype of RCA male split cable that is designed, created for the GA EX-58 rear speaker out jack (black) that goes out to two 4/5.1 read surround speakers that I am not finding or .... ??

Help. Please advise.

John

and, then, some such RCA male
