I bought from KnuKonceptz. VERY happy and not too $$$. I actually got it last year when some of the wire was on sale. I have 10 ga (karma) for my fronts and center, and 12 ga (klear) for the QS8s. (yeah, i know the 10 ga would make sense for the longer run, but doesn't seem to make a difference.)

Partsexpress is highly regarded, as is home depot. can't go wrong w/ either.
