Mounting Solution

The Wet Sounds Billet WS420-SQ BT Knob Under Dash Mount in black is designed specifically for the WS-420BT unit. It provides a secure way to install the head unit beneath the dashboard without cutting an opening in the dash panel. This accessory suits marine or automotive owners who want a clean, integrated look for their audio control. It keeps the receiver accessible while preserving the original dashboard surface.

Compatibility Constraint

This mount is built exclusively for the WS-420BT model and will not fit other head units. Buyers with different receivers need a separate mounting kit. The design relies on the specific chassis dimensions of that single product. Installers must verify they have the correct controller before purchasing this bracket.
