The STX Micro-1 is the monoblock subwoofer model in Wet Sounds’ Stealth STX Micro Series — a compact, sealed Class-D amplifier engineered for powersports enthusiasts and any installation where space is severely limited but subwoofer performance is still the priority. At just 9.25″ long, 4″ wide, and 1.5″ high, the STX Micro-1 delivers genuine subwoofer output in a chassis that fits virtually anywhere.

The completely sealed die-cast aluminium chassis provides maximum protection against water and dirt intrusion — equally suited to ATV, UTV, and marine applications where exposure to the elements is constant. 3.5mm signal input connections allow seamless integration with Wet Sounds Bluetooth controllers or direct connection to most smartphone headphone outputs, keeping the installation clean and straightforward.

Output power of 250W at 4Ω, 420W at 2Ω, or 600W at 1Ω gives the STX Micro-1 the headroom to drive a dedicated marine subwoofer effectively. Fully variable bass boost allows fine-tuned low-frequency adjustment to suit the enclosure and listening preference, while the adjustable low-pass crossover provides precise control over the subwoofer’s upper frequency limit. With a frequency response extending from 10Hz to 250Hz and a signal-to-noise ratio of over 95dB, the STX Micro-1 delivers clean, powerful bass output well beyond what its compact size might suggest. Backed by Wet Sounds’ 2-year limited warranty.
