I am attempting to make my own speaker cables. I have bought 12 gauge wire from axiom, GLS locking banana plugs,braided sleeving,shrink tube and the cable pants. This is a little harder than it seems. My main issue is I cant even begin to get the wire to fit into the cable pants. I bought the large 14mm size as well as the 11mm size. I tried using liquid laundry soap on the wire insulation but it just wont go. Any ideas on how to get the wire to slip through the pant leg?
