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.
