Speaker wire is Class 2 low-voltage and needs no special insulation or ratings for use by itself or with other speaker wire in conduit of any type. Do not run with AC power lines.
For 50 feet, losses will be negligible with any modern audio power amplifier; I use 16 ga. for that length run at my place.
I would avoid 50' runs of line-level signals from unbalanced sources -- line-level outputs on typical consumer audio gear are driven from relatively high impedance sources, often over 1kOhm, potentially causing frequency response losses due to cable capacitance.
