Upgrade your Car, Boat, Motorcycle, or ATV’s factory speaker set with the DB+ Series to get that legendary Polk sound wherever life takes you. You’ll get loud, crystal clear sound with effortless bass from a marine certified speaker that’s easy to install and built to last.
The DB+ Series is IP56 rated so they are dirt- and water-resistant. They also have been tested for salt-fog, UV and humidity. A big part of that marine certification also means that each speaker has a non-corrosive plastic grille, a polypropylene UV tolerant cone, waterproof inner and outer surrounds, and stainless steel mounting hardware, ensuring that they are fully protected against the elements.

Purchased on sale
Used these on the outside of my travel trailer. They sound amazing! I gave 4 stars on ( Look ) only because I don't really care for the grills, which is personal preference.

Great speakers!
My dad loves these! They produce a great sound and are quite loud. A really good bargain.
Too small for Volvo v-70 rear door without adjusting.

Polk Audio DB522 DB+ 5.25-inch (DB 522)
Replaced the old speakers in a 2008 boat. These have good highs and put out a tight bass. You can definitely tell a difference. They do not distort when you crank it. Happy customer

Perfect for soundbar in Jeep
You can’t beat these for price. Installed in 97 Jeep TJ sound bar. Fit stick holes perfect and sound great. Nice crisp highs and mids with no distortion even at max volume.
