  • TypeAmplifier
  • Amplifier Channels1
  • Delivers 600 watts RMS at 1 ohm for maximum bass impact
  • Stable down to 1 ohm load for flexible subwoofer wiring options

  • Three-way protection circuitry safeguards against thermal, overload and short-circuit faults

Powersport monoblock for marine installs

The Wet Sounds STX Micro-1 is a Class-D monoblock amplifier built for powersport and marine environments. Its ultra-compact chassis fits tight compartments on boats, side-by-sides or personal watercraft. The 1-ohm stable design supports low-impedance subwoofer loads without shutting down.

600 W RMS at 1 ohm with CEA-2006 ratings

Continuous output reaches 250 W at 4 ohms, 420 W at 2 ohms and 600 W at 1 ohm, all measured to the CEA-2006 standard. Frequency response spans 10–250 Hz with THD of 0.19 % and a signal-to-noise ratio above 95 dB. Input sensitivity adjusts from 150 mV to 7 V for flexible source matching.

Replaces larger amps when space is the limit

The heavy-duty aluminium heat-sink and three-way protection (thermal, overload, short) allow high power in a footprint that full-size monoblocks cannot match. It is not for installs that need multi-channel output or full-range frequency response beyond 250 Hz.

Questions about this item

Will the STX Micro-1 1-channel amplifier work with my existing 4-ohm subwoofer?

Yes, it delivers 250 watts RMS into a 4-ohm load and remains stable down to 1 ohm, so your current subwoofer will run within the amplifier's rated range.

How can I confirm the amplifier is operating normally once installed?

The green LED indicates power is on, the red LED lights only during a protection event, and the soft-start circuit prevents turn-on thump so silence at power-up means the circuit is healthy.

What comes with the STX Micro-1 and what must I supply separately?

The box contains the monoblock amplifier with its heavy-duty aluminum heat-sink and built-in protection circuitry; you will need to provide power and ground wiring, RCA signal cables, speaker wire and a suitable fuse block.
