4 x Polk Audio MM 6.5 inch 2-Way Car Marine Audio Boat Motorcycle Coaxial Speakers 6-1/2"

Upgraded from the the DB652 and the difference is night and day. I have these in my lower fairings on my 2k Road King Classic and I just installed 4 of these in upper and lower fairings on a 2012 Road Glide. The sound quality is UNBELIEVABLE!!!Originally were attracted due to the ultra marine benefit

Running 2 in the upper fairing and 2 in my lowers on my 2018 Street Glide Special. The sound is amazing, lots of clarity and very loud. Replace Hertz mille pros. Running 8 speakers in parallel, including 4 Polk 6x9s with a Biketronics 4180 Amp. Killer setup!!!

I bought a set of these to replace my Harley Boom stage 1 speakers. They are by far a lot better quality, sound is crisper and cleaner and they have not blown on me yet. My Harley Boom speakers I have had at least one blow every season. Had them for a full riding season and they are pretty loud. Not one has blown either. Great product.

Sound is perfect, replaced my old Polk mm’s. The grills are more like a car not a good look on a boat. I purchased replacement grills.

Much better quality speakers than the DB652s that they replaced.

I put 4 of these on my 08 Harley 2 in upper and 2 in lower fairing. Pushed by a 300.4 Rockford amp. Sounds amazing

Very good sound quality for a marine grade speaker...great job Polk Audio!!!!

Sound great in my 14 ultra limited
