Subwoofer Wedge

thingiverse

This straightforward insert printed in flexible material will effectively suppress vibration on the rear deck of the 2016 and 2017 Honda Civic Touring. Simply position the insert between the front edge of the opening for the 3rd (center) brake light and the brake light housing. The pressure exerted by the insert keeps the back deck from vibrating with the low-frequency sound produced by the car's subwoofer.
