GoHawk TR42-Titan 4.1-Channel Waterproof Bluetooth Amplifier for Motorcycle/ATV with 2×4.25" Chrome Speakers, Passive Radiators, USB, FM & 600W Sub Out

The GoHawk TR42-Titan is our flagship — the first waterproof 4.1-channel amplifier designed for motorcycles, Harley Davidson installs, ATVs, 4-wheelers and UTVs. It powers up to four full-range speakers plus one subwoofer (Not included) and ships with two 4.25" chrome speakers, each fitted with a 1.6" passive radiator mounted on the rear to boost bass response. The compact amplifier features a brushed aluminum housing, sleek top cover with a chrome-finish ring and a low-profile blue LED power indicator centered on top. An attached braided-sleeve connection cable (overall 27" length) feeds the unit, and a separate full-function backlit wired control lets you navigate playback and settings with ease. Audio inputs and outputs: USB playback (USB drive play only — charging not supported), 3.5mm AUX-IN, FM radio with external antenna via standard SMA connection, and a dedicated subwoofer output rated at 600W Peak (subwoofer output is not available in the FM radio function). Wireless: standalone Bluetooth antenna connector with Bluetooth 5.0 allows streaming up to 15 meters; compatible with iPhone 11 / 12 / 13 / 14 / 15 / 16 Pro Max, iPod, iPad, Samsung Android Galaxy S A M Z Series and Any Smartphone Devices. Built for outdoor use with advanced IP56 waterproof protection. Installation is plug-and-play with a standard 12V power connection and includes all necessary hardware and wiring, two antennas (FM radio & Bluetooth) and a 78" long SAE to ring-terminal power cable for easy setup.
