Polk Audio DB652 6.5" Coaxial Speakers — Four Pairs (Marine & Powersports Certified)

Built for harsh environments, the DB+ Series (DB652) carries an IP65 rating for water and dirt resistance and has been tested for salt-fog, UV and humidity exposure. That rugged validation makes these 6.5" coaxial speakers a great upgrade from stock systems in cars, trucks, boats, side-by-sides and similar vehicles, delivering a larger, fuller sound than typical OEM speakers. Constructed from high-grade materials and incorporating Polk’s Dynamic Balance technology, the DB+ delivers clear, full-range audio while lasting longer than factory units. Installation is straightforward: the updated DB+ design offers a universal drop-in fit and a shallower tweeter so your original speaker grille can be reinstalled for a clean, flush appearance in automobiles, motorcycles, boats, ATVs and more. Both the inner and outer surrounds are waterproof, preventing dirt, liquids and grime from entering the speaker housing—helping to minimize corrosion and extend the service life of the speaker and its basket.
