Enjoy stellar sound
The specialists at Alpine optimize their SPS-610C component speakers for great range and impressive tone definition, even at low power levels. You can connect these versatile Type-S Series speakers to your factory stereo for an immediate sonic improvement, or hook them up to a powerful aftermarket stereo or amp for increased performance.
 
Mineral-fortified polypropylene cones are exceptionally stiff, yet lightweight, which means they can push out accurate bass and deliver clear midrange. Resilient rubber surrounds help keep the woofer centered for accurate cone movement, reducing distortion. You can aim the separate silk dome tweeters toward you so that they deliver the strongest possible stereo image.
 
Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.
 
Grilles are not included; the factory grilles should be suitable for most applications.
