Cheapo interconnect for sub only

Hey folks,

I'm contemplating purchasing a longish (4-5M) stereo pair of interconnects to run from the preouts of my integrated to a sub (not an REL--I'm not going to use the speaker terminals). Since my experience has been that most interconnects excel in one area but not necessarily all, does anyone have one to recommend that provides tight, fast, deep bass, all other considerations being irrelevant? I have found that sometimes brighter interconnects have tighter bass which would work here, since I wouldn't have to worry about the mids and highs puncturing my eardrums. Anyone know of something that wouldn't break the bank (say up to $200 used, preferably less) at that length? Any suggestions are welcome.

Thanks,

Jeff
