About the Kicker 51KXMA15001
From our tech experts at CEN
A marine-rated amplifier, 1 channel, rated at 1500w RMS, coated to cope with damp and salt air where a car amplifier would corrode.
Who it suits
Boats, ribs and open builds, and anywhere an amplifier is mounted somewhere it will get damp. Campers with outdoor speakers are an increasingly common use.
Our tech experts advise
Mount it somewhere ventilated and as dry as the boat allows, and fuse the feed at the battery. Marine wiring wants tinned cable and sealed joints. get in touch to talk through the install. See car audio installation.
