Subwoofer Powercord & IC Recommendations

Can you recommend me a good powercord to hook up a subwoofer and give me an idea if there are interconnects specifically made to hook up a sub? I would like to hear from members who went to an aftermarket pc and what differences there were.Ditto on the ic's

Inexpensive but effective sub cable: Blue jeans. Don't have comparison information but it gets the job done.
