Any problems using biwire cbls on single post Spkr

I have single post speaker connections on my Klipsch Chorus II speakers. I am looking to buy a set of AudioQuest Crystal wires that are internal bi-wired with spades. My intentions are to put the 2 positive spades on the positive post and the same way for the negative. The Crystal is a very thick cable, can they be connected this way? Are there any sonic effects in doing it this way, Good/Bad?
Any responses would be greatly appreciated!
