As far a speaker wire goes, go down to Home Depot or Lowes and get some 12 or 14 gauge lamp cord in whatever length you need and tie it into you system using bare wire connections. Make sure none of the little strands touch any of the other terminals or the cabinet. 12 gauge lamp cord will handle much more power than you are ever going to put to your speakers, unless you amplifiers doubles as an arc welder. At $.30 per foot you can afford the $20 risk before you take the plunge into speaker wire which costs more than a car loan.
