If I wanted to make my own speaker cables, is this a good choice for wire?

Duelund Dual DCA16GA 2x16 awg, Tin-plated, Stranded Copper, Oiled Cotton Speaker/Interconnect Cable

I'm thinking this wire and adding some quality banana plugs or RCA connectors to make interconnects.  Is 2x16 enough or should I double up?  Is shielding an issue?  Thanks!
