It's up to you if you want to change your speaker wire. I asked about speaker wire at one point when I was scoping things out (I'm still doing it. You've got a faster trigger finger or bigger wallet than me )

and one of our highly regarded guru's here (Sushi) recommended http://www.partsexpress.com/pe/pshowdetl.cfm?&PartNumber=100-155&DID=7

It's inexpensive and 12AWG which should be more than sufficient.

Hope this helps.
