Our take on the Wet Sounds WS 420 SQ

by Jon Paulette

Maximize your marine stereo

Take control of your marine audio system with the Wet Sounds WS-420SQ equalizer. This compact, powerful device combines state-of-the-art technology and smart features to help you get the most out of your boat's audio system. Wet Sounds designed this powerful equalizer for marine use, with a conformal-coated circuit board that resists corrosion and rugged construction that can stand up to the rigors of life on the water.

Here's how it works

With two separate EQs in one ultra-compact half-DIN chassis, this 3-zone device gives you independent control over the volume of your tower speakers, in-boat speakers, and marine sub. You'll also enjoy independent control over the EQ on your in-boat and tower speakers, so you can customize the tone of each to suit your tastes. If you're hanging out at the dock, just use the in-boat speakers. If you're out on the water, crank up the towers and the sub and let it rock.

Smart features designed for boaters

Wet Sounds marine stereo gear is designed by boaters for boaters, so there are plenty of smart touches that you'll appreciate when you're having fun on the water. You can use the system's "talk back" microphone to communicate with your crew, the water skier you're towing, or other boats in the area. When you push the mic button, the system mutes the music coming out of the tower speakers, so you can use them as a PA system. Once the button is released, the tower speakers will begin to play again at the previous level. It's simple, smart, and safe.

The WS-420SQ is also equipped with Boat Link™, a Wet Sounds exclusive. With Boat Link, you can create a true "party cove" when you're tied up to another WS 420SQ-equipped boat. All you need to do is plug a long cable into the rear 3.5mm jack and run it to your neighbor's WS 420SQ. You can both enjoy the same music, while retaining individual volume control. It works on multiple boats too, so the more, the merrier.
