By wire I assume you mean speaker wire. Most HTIB's comes with speaker wire in the box. This is usually thin, low grade wire. But it is easy to hide. If you plan on cranking up your SS system from time to time (and I'm sure you are), I recommend uprading your speaker wire. I went with 16 guage speaker wire. You can get a spool for realtivly cheap and is well worth it IMO. I used the AR spool I got from CC I think. BB sells a AR 50' spool for around $25. You can find it a bit cheaper online.
