    Is 16 guage sufficient for a 50 ft speaker cable connecting a 500W (program not peak) speaker, or should I go with the 12 guage?

    I need four so I'll save some coins with the 16 guage...I just don't want to inhibit the signal/speaker power.

    For a 50 foot run I'd use at least 14 gauge. Anything longer (up to 100 ft) definately use 12 gauge.

    It's less a matter of how much power and more a matter of load impedance.

    For a long cable run feeding a 2-ohm load, you're not going to get away with the wire resistance that you could with an 8-ohm load.

    If you make your own cables, the difference in price between 12 and 16 gauge wire isn't much. If I were making a 50-foot speaker cable, I'd make it 12 gauge.
  5. Yea, it depends on the speaker load.
    14 ga. is a great all round size ! :hyper:
