Memphis Audio MXA18SW50

The Memphis Audio MXA18SW50 is a 50-foot spool of 18 AWG parallel speaker wire for marine and powersports audio installations. Its tinned oxygen-free copper conductors are designed to resist corrosion in outdoor environments. Use it to connect compatible speakers to an amplifier or source unit when laying out a boat, ATV or side-by-side audio system.

The parallel cable format keeps the speaker conductors together along the installation route. Calculate each cable run and confirm that 18 AWG wire meets the speaker load, amplifier output and total distance requirements before ordering. Maintain consistent polarity at every connection, protect the cable where it passes through panels and secure it away from moving parts and heat. This is speaker cable; amplifier power and RGB lighting circuits require their own correctly specified wiring.
