Amp up your off-roading Finding space for an amplifier on an ATV used to be difficult to impossible. Not anymore. ATVs are getting bigger and amps, like this Wet Sounds STX Micro-4, for example, are getting smaller. So if you want to enjoy your music to the max, this compact, powerful Class D amp will bring out the best in your Wet Sounds speakers. Made for outdoor use Wet Sounds designed this 4-channel amp to stand up to whatever the great outdoors - or your riding style - can dish out. The die-cast aluminum chassis is specially sealed to keep water and dirt away from the internal componentry. Its small enough to fit an ATV, and its also ideal for boats, golf carts, and more. Plenty of power But dont let the compact exterior fool you. Inside this little dynamo is some sophisticated tech that pumps out plenty of sound. The STX Micro-4 boasts a rated output of 80 watts x 4 channels at 4 ohms, or 130 watts x 4 at 2 ohms. You can bridge the amp to 2-channel mode to drive a pair of 4-ohm subs with 280 watts RMS each. Fully variable high- and low-pass filters allow you to tailor the amp for the job at hand. Lots of volume, lots of versatility A set of pass-through outputs allow you to connect a second amp, like the STX Micro-1 sub amp. And multichannel switching mode lets you get four channels of output with only two channels of input - you wont even need Y-adapters. The 3.5mm minijack input works with Wet Sounds Bluetooth controllers or almost any outboard audio device, including your smartphone.
