- CONTROLLER: This easy-to-install controller with Bluetooth wireless technology puts audio controls at your fingertips. It allows users to control the volume independently for three zones or simultaneously on the primary setting. An LED backlight on the remote indicates which zone is active. The controller is equipped with built-in connectivity with Bluetooth technology and auxiliary input. A high-quality internal digital signal processor produces lossless audio output to your sound system.
- AMPLIFIER: Using a Class-D power plant, this amp features a variable bass boost, giving you as much as 6dB of extra bump. Powering as many as eight speakers, this amplifier makes your entire boat sound like a floating concert! A powerful 12dB crossover is also included, letting you quickly tune your system to perfection. This KM-Series amplifier delivers 90 watts into four channels, or 180 watts bridged into two channels.
- AMPLIFIER INSTALL KIT: Power your marine amplifier with a wiring kit that can withstand the harsh environment and still deliver full sound performance. Fully wiring ensures that these amp kits won’t corrode or oxidize and turn green after a season on the water. Oxygen-free copper provides a reliable connection with maximum conductivity. By using 100% virgin copper the tin won’t flake off, something commonly seen when using recycled copper materials.
