The STX Micro-1 and STX Micro-4 Compact chassis Class D Amplifiers by Wet Sounds, are the latest innovative products designed for the Power Sports enthusiast. The small yet powerful amplifiers are designed with a completely sealed die cast aluminum chassis for maximum protection against water and dirt intrusion. Both STX models are outfitted with 3.5mm signal input connections to work seamlessly with our Bluetooth controllers (BTVCC) or direct connection to most smart phone’s headphone output. The STX Micro-1 mono block subwoofer amplifier has output power capability of 420Wx1 into 2 Ohms & 600 Wx1 into 1 Ohm and also includes fully variable Bass Boost and adjustable low pass crossover. The STX Micro-4 has a rated output power capability of 80wx4 into 4 Ohms & 130 Wx4 into 2 Ohms. Bridged power on the STX Micro-4 is 280Wx2 into 4 Ohms, with fully variable high pass/low pass crossovers. A set of pass-through outputs on the STX Micro-4 allows connection to a second amplifier, and the multichannel switching mode enables all four channels of output with only 2 channels of input, eliminating the need for Y adaptors.
