Next-level Polk speakers

We're big fans of Polk speakers for their reliability and precise sound, and their premium Mobile Monitor Series MM 522 5-1/4" car speakers only improve on that well-earned reputation. You can count on low distortion and maximum performance from this flagship Polk line, the result of years of research and development. These rugged car speakers are ultra-marine certified, able to shrug off harsh environmental abuse to deliver exceptional sound for nearly any application, from cars to boats.

Perfect for any power source

The highly efficient speakers will work well with an aftermarket radio, but keep in mind that they will really show off their stuff with a lot of power from an aftermarket amp. The titanium-coated 5-1/4" polymer woofer cone, backed by a space-efficient magnet, delivers the full sound you've been hungry for. A low-profile, lightweight carbon basket features excellent venting to keep these speakers cool when you're really pouring on the power. And your music's high frequencies will soar, thanks to delicate handling by the newly designed 1" Terylene fabric dome tweeter.

Product Research

Features

Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

Rubber Surrounds: The inner and outer woofer surrounds are Santoprene rubber, to keep water from leaking through the speaker.

Swivel Tweeters: The 1" tweeters pivot, so they can be angled for optimum imaging. The tweeter material is Terylene, a brand name of polyethylene terephthalate (PET).

Neodymium Magnets: The speakers' neodymium magnets offer exceptional strength to performance ratio and are small and lightweight.

Basket: The speaker baskets are fiberglass reinforced ABS, lightweight and corrosion resistant.

Crossover: The crossover components are coated with epoxy to prevent corrosion. The low pass filter is 1st order (6 dB/octave) and the high pass filter is 2nd order (12 dB/octave).

Ultra-Marine Certified: Polk MM1 Series speakers are tested to withstand exposure to salt-fog, UV rays, and humidity, so they'll work well in boats and cars. They also include stainless mounting hardware for corrosion resistance.

Drainage: The speaker should be mounted so the slots along the perimeter of one side of the basket are at the bottom, so any water trapped between the speaker and grille can drain.

Terminals: These speakers have 0.25" positive (+) terminals and 0.187" negative (-) terminals, which are too large for the speaker harnesses supplied by Crutchfield for many vehicle-specific applications. The speaker wire included by Polk Audio has the correct size terminals attached, so that can be spliced to an adapter harness, or optional crimp-on female quick slides can be purchased (item number 120FQS10PK, sold separately).

Thanks for your question. For information on selecting the best amp I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.

I do not know. They fit in the factory speaker holes for a 2006 Chevy Silverado (extend a cab) front door speakers. If you do not find the answer anther way perhaps you can research what the stock hole size is for my truck.
