Connecting a vintage receiver/amp to new speakers

[mls13]

Hi all
I picked up an old and generally crappy Pyramid turntable/cassette/radio.
http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=180749993761&ssPageName=ADME:L:OU:US:1123#ht_500wt_922

I love it. But it has old style RCA speaker inputs and I have no idea how to connect more modern speakers with your typical + and - connections. The inputs are: front left, front right, rear left, rear right, and aux left and aux right. Each one (6 total) is a single RCA input.

I connected a single speaker wire to an RCA adapter today, with no regard to the ground hole in the adapter. I just screwed the wire into the end of the adapter. Then I split the other end into two strands and fed them into the back of the speaker. This did not work and I am assuming it was a polarity thing.

Help is much appreciated! I clearly don't know what I'm doing.

Thanks

The speaker connections on the pyramid are OUTPUTS not inputs!
An RCA speaker cable can be bought from radio shack, strip the wires back and connect it to the speaker.
Be Careful. if you cross the wires together, it will short circuit the pyramid.
