About the AudioControl ACM-1.300
From our tech experts at CEN
A monoblock subwoofer amplifier from AudioControl, in a micro chassis small enough to hide behind a panel, rated at 300w RMS.
Who it suits
Anyone adding a subwoofer that needs controlled power rather than a compact powered unit. Micro amplifiers are the answer in modern cars and vans where there is nowhere to put a full-size chassis. 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.
