Greg,
The first response is correct, but I will add some detail for the "un-inititated".
Generally quality interconnect cables come as a pair of two seperate cables. One generally has red markings on the connectors and the other generally has black or white markings on the connectors.
The standard wiring for audio is "Red=Right channel, Black/white=Left connection".
Connect the "red" interconnect from the right output of you pre-amp to the amp you will use to drive the right speaker. Connect the "black/white" inerconnect from the left output of your pre-amp to the amp that will drive your left speaker.
Lastly, if the interconnects have arrows on them, typically the arrows point away from source and ultimately toward speakers, so if you interconnects have arrows, the arrows point away from your pre-amp and toward your amp.
Actually it may not be important to follow the "red=right" or the "arrows toward speaker", however, if you do this every time, you will always be consistent and you are less likely to ever make a mistake.
Enjoy,
TIC
