About the AudioControl ACX-300.1
From our tech experts at CEN
A monoblock subwoofer amplifier from AudioControl, all-weather rated for powersports, marine and open builds, rated at 300w RMS.
Who it suits
Anyone adding a subwoofer that needs controlled power rather than a compact powered unit. The sealed, coated build suits boats, buggies and anything that gets wet. AudioControl built its name on signal processing, and that thinking runs through the amplifiers too.
Our tech experts advise
Matching matters more than headline watts, the gains want setting with a meter, and it needs a fused feed from the battery on the correct cable gauge. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.
