Wet Sounds STX MICRO-1 Class-D Monoblock Marine Amplifier 600W

The Wet Sounds STX MICRO-1 is a compact Class-D monoblock subwoofer amplifier built for marine and powersports applications where space is at a premium. Delivering up to 600 watts RMS at 1 ohm, this ultra-small amp punches well above its weight class and is engineered to thrive in the harshest outdoor environments.

The STX MICRO-1 features a fully sealed die-cast aluminum chassis that provides robust protection against water and dirt intrusion, making it ideal for boats, ATVs, UTVs, golf carts, and other powersports vehicles. Its IPX6 water-resistance rating and marine-rated components ensure long-term reliability wherever the ride takes you.

At just 9.25" L x 4" W x 1.5" H, the MICRO-1 fits behind panels, under seats, and in storage compartments that would be impossible for a traditional amplifier. A 3.5mm signal input allows direct connection to Wet Sounds Bluetooth controllers (BTVCC) or most smartphone headphone outputs for simplified source integration.
