Hertz Cento C 165L 6.5" Woofers, 80W RMS, 4Ω, Pair

Hertz Cento C 165 L is a 6.5" (165 mm) midbass woofer designed for strong low-frequency response and clean, controlled output in door and factory speaker locations. It uses a water-repellent non-pressed paper (NPP) cone to keep a natural tonality while improving durability for real-world installs.

Built around a high-density ferrite motor and a 25 mm (1") voice coil on an aluminum former, the C 165 L is engineered to handle power and maintain control at higher excursion—ideal for OEM upgrades that need more midbass impact without getting sloppy.

Fitment & Installation Notes

• This is a pair of midbass woofers, not a complete component speaker set. Tweeters, crossover/DSP and installation parts are separate. Confirm cutout, mounting depth, clearance and adapters; a 6.5-inch label alone does not guarantee vehicle fit.
• Works best in a properly treated door (deadening + sealing) for real midbass gain
• Commonly used as the woofer section in a 2-way component setup with an external crossover or DSP

Buyer Use Cases

• OEM speaker upgrade focused on midbass punch and cleaner lower vocals
• Building a Cento-based component system (woofer + tweeter + crossover/DSP)
• Upgrading door speakers while keeping the factory head unit (with proper amplification if needed)
