what kind of subwoofer cable to buy? Y- or single

What kind of subwoofer cable is everyone using? I have a Paradigm PW-2200 sub and a Marantz SR-7300ose. The direct mode sounds best but it bypasses the base management. Is there a way that I can set this up so I can use my sub in the direct mode? Any feedbacks would be greatly appreciated. Thanks

Tributaries makes a great Y subwoofer cable, check out Ebay.

Good Luck!
