Infinity Car Subwoofers Information


There aren't many subwoofers that deliver the same bang-for-the-buck that Infinity offers. Infinity car subwoofers are a compact yet effective way to add heart-pounding bass to any car. The engineering behind the Infinity subwoofers allows them to play the deep, rich window-rattling bass that makes them one of the most popular options available. The Infinity Reference and Kappa series car subwoofers separate themselves from the pack by providing the quality and reliability you've come to expect from Infinity.

The incredibly deep bass response of the Reference series commands respect thanks to the strong, lightweight Mica reinforced composite cone. The GS series subwoofers are capable of delivering up to 1200 watts of hard hitting sound and their large roll rubber surround absorbs any unwanted distortions.

The Kappa subs are also capable of producing deep lows that will really bump with their coated glass fiber cones and thick rubber surround. Infinity designed the Kappa subs with Selectable Smart Impedance technology which allows you to run them at 2 Ohms or 4 Ohms with the flick of a switch.

Infinity subwoofers are available in 8", 10" and 12" designs and are a perfect fit for most vehicles. High energy Ferrite magnets control the cone travel in all Infinity subwoofers to deliver some of the strongest sounds on the market.

So what are you waiting for? Pick up a Infinity Car Subwoofer today!
