Wet Sounds STX MICRO-4

The Wet Sounds STX MICRO-4 Compact Chassis Class-D 4-Channel Marine Amplifier is engineered for marine and powersports audio systems where installation space is limited but high-performance amplification is essential. Featuring a fully sealed die-cast aluminum chassis, the STX MICRO-4 is built to withstand water, dirt, vibration, and harsh environmental conditions while delivering reliable, consistent audio performance. Its high-efficiency Class-D design provides strong multi-channel output with minimal heat generation, making it ideal for mounting in confined spaces such as under seats, behind panels, or inside storage compartments. The compact footprint allows for flexible installation without sacrificing power or sound quality. The STX MICRO-4 features a 3.5mm signal input for seamless integration with Wet Sounds Bluetooth controllers (BTVCC) or direct connection to compatible smartphones and portable audio devices. Pass-through outputs simplify future system expansion, while multichannel switching mode allows all four output channels to operate from only two input channels, eliminating the need for Y-adapters. Fully variable high-pass and low-pass crossovers, along with bridgeable channels, provide flexible tuning and configuration options for a wide range of speaker system designs.
