Hertz CS 300 S2

$330.00

Cento Series 12″ shallow-mount 2-ohm component subwoofer

Designed to fit. With over two decades of experience, Hertz knows how to build great-sounding car audio gear, and their speakers, subs, and amps get raves from customers. They designed the CS 300 S2 shallow-mount 12″ subwoofer to get powerful bass from a very small enclosure, and its reasonable 5-1/4″ mounting depth allows installation in the smaller spaces of today’s cars.

The CS 300 S2 subwoofer features a rugged polypropylene cone that punches out deep, rich bass, while minimizing distortion. The sub handles up to 350 watts RMS, and its 2-ohm impedance makes it a great match for a mono sub amp. Push terminals accept up to 8-gauge speaker wire so you can maximize the signal delivered to the speaker.

This sub is designed to mount close to the back wall of your enclosure and requires very little clearance in front. It’s optimized for enclosures as small as 1.13 cubic feet, so it will tuck into a corner of the trunk or under the rear seat of many trucks. A tough PVC gasket lets you install Hertz’ CG 300 speaker grille (sold separately) for extra speaker protection and a clean, finished look.
