Below you will note basic guidelines for outdoor speaker cable in the form of charts for outdoor speaker burial cable runs with allowances for resistance down the line and or power / voltage drops incurred. Besides power consumption loss, resistance in a cable run has a very detrimental effect upon sound quality and output power.
While the guides below are generally useful for outdoor speaker burial cable it should also be noted that specific, local installation conditions, connections integrity and wire quality including copper quality content of the cable itself, all have an effect upon resistance down the line and therefore your ultimate performance characteristics.
outdoor speaker burial cable wiring specifics
According to the consumerreports.org outdoor speaker wireless models are not recommended; "Among the wireless sets we tested, they were prone to interference from devices such as cordless phones, microwave, resulting in static, hissing or clicking". They have high failure rate for a frequency transmitter, their sound quality is AM radio comparable and made of fragile plastics components which can easily break."

| The above chart shows wire gauges to be used, if no less than .5 volt drop is accepted. If aluminum wire or tinned wire is used, the gauges should be of an even larger size to compensate. Cable gauge size calculation takes into account terminal resistance. Wire gauge recommendations based on IASCA guidelines. |
