This new J&M ROKKER® 4-channel 400-watt RMS fairing/rear speaker amplifier kit has been designed specifically for use on the 2018-2022 Honda® GoldWing Tour or Standard models. 100% plug-n-play into the Goldwing’s electrical system and provides 4 separate channels of amplification at 100 watts RMS continuous power per-channel into a 2 or 3-ohm speaker load.
