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 our customers. They designed the CS 300 S4 shallow-mount 12" subwoofer to get powerful bass from a very small enclosure, and its 5-1/8" mounting depth allows installation in the smaller spaces of today's cars.

Tough enough

The CS 300 S4 12" subwoofer features a rugged polypropylene cone that punches out deep, rich bass, while minimizing distortion. The sub handles up to 350 watts of RMS power, and its 4-ohm impedance gives you plenty of options for wiring your system. Push terminals accept up to 8-gauge speaker wire so you can maximize the signal delivered to the speaker.

Minimal clearance needed

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.

For big bass in a small space, the CS 300 S4 is engineered to excel. You'll get the thump you're looking for in a rugged subwoofer that'll vanish in the corners of your vehicle.
