RCA AH18100R 100 ft. 18-Gauge Speaker Wire

The RCA AH18100R is a 100-foot spool of 18-gauge speaker wire designed for connecting passive speakers to amplifiers, A/V receivers, and stereo systems. The wire uses a clear plastic jacket that makes conductor identification simple — a printed marking or molded ridge along one side distinguishes the positive conductor from the negative, which is essential for maintaining correct polarity across multiple speaker connections and avoiding phase cancellation in stereo or surround setups. The 18-gauge copper conductors provide adequate current-carrying capacity for most home audio applications at typical listening volumes.

Installation is straightforward: cut the spool to the desired length, strip roughly half an inch of insulation from each conductor, and connect to the speaker and amplifier terminals. The wire splits easily along its center seam for separation into individual conductors where needed. At 100 feet, the spool provides enough wire to connect several speakers in a single room or to make a longer run to a pair of speakers in an adjacent space. While it lacks the heavier gauge and specialized jacketing of premium speaker cable, the RCA AH18100R serves its purpose well as an affordable, reliable connection for everyday home audio systems.
