The Wet Sounds WS-420SQ offers equalization and volume control of three primary zones of your audio system in one sleek chassis.

The Wet Sounds WS-420 SQ Multi-Zone Parametric Equalizer is a state of the art 4-band equalizer designed to provide amazing control and flexibility of your marine audio system. The WS-420 SQ is a 3-Zone equalizer/controller with 2 separate equalizers in one half din chassis using Wet Sounds' exclusive design which allows you to independently control the volume of tower speakers, in-boat speakers, and subwoofers all independently and have EQ adjustments of both in boat and tower speakers independently. The WS-420 SQ is Wet Sounds' award winning platform that has set the standard for marine audio system control.

The Wet Sounds WS-420 SQ Multi-Zone Parametric Equalizer also features a talkback microphone option to easily communicate with your rider or other boats. By pushing the button on the microphone, the system automatically mutes the music playing from the tower speakers and allows you to use your tower speakers as a PA system. Once the button is released, the tower speakers will begin to play again at the level they were at.

Additionally, the WS-420 SQ includes Wet Sounds exclusive Boat Link. Boat Link gives you the ability to link up with other boats equipped with Boat Link for the ultimate party cove experience.
