Hertz CPK 165 | Cento Pro Series 6.5" 2-Way Component System
The Hertz CPK 165 is the "Pro" evolution of the Cento line, bridging the gap between high-end performance and installation flexibility. Featuring the CP 165 woofer and the CP 25 Tetolon dome tweeter, this system is designed for the enthusiast who wants a more sophisticated, linear frequency response and a realistic soundstage. With materials inherited from the flagship Mille Pro line, the CPK 165 provides an "audiophile" experience with the power to handle high-energy dynamic transients with ease.
Product Highlights
-
Mille Pro Inherited Materials: The woofer cone is crafted from pressed paper with a geometry optimized via FEM (Finite Element Modeling). Combined with a butyl rubber suspension, these materials provide excellent damping and lightness for a balanced sound without resonance peaks.
-
CP 25 Tetolon® Dome Tweeter: This 29 mm (1.14 in.) tweeter features "Center Tuning Duct" technology—a tunnel at the center of the magnetic circuit that ensures low-temperature air exchange and perfectly tunes the acoustics for a low resonance frequency ($Fs$).
-
Advanced Crossover (CPCX 2): The included passive crossovers feature a three-position tweeter level switch (-2, 0, +2 dB). This allows you to customize the high-frequency balance based on your car's acoustics or your personal preference.
-
Enhanced Cooling System: The woofer's motor assembly is designed for high thermal stability. The high-density flux ferrite magnet and low-carbon polar plates ensure that even at high volumes, the system remains cool and provides undistorted, punchy mid-bass.
Key Features
-
Vibration Damping: The compact three-spoke basket is combined with an anti-vibration rubber magnet cover. This ensures that spurious vibrations don't color your music, keeping the output clean and transparent.
-
Linear Off-Axis Response: The faceplate geometry of the CP 25 tweeter is optimized with FEM technology. This is critical for car audio, as it ensures a smooth frequency response even when the speakers are mounted in off-axis factory locations.
-
High Power Handling: Rated at 105W RMS, this system is built to thrive when paired with high-quality aftermarket amplification, though its 92.5 dB sensitivity still makes it efficient enough for premium head units.
-
Premium Grilles Included: The system comes with stylish, high-resistance ABS plastic grilles with a metallic finish and protective mesh, offering both a sophisticated look and durable protection for the woofers.

What Others Are Saying
Eddie was great - SDCS installed a new head unit in my 2019 4Runner. He was honest in his opinions regarding the options I was considering. Pricing was also good - he was able to reuse some of my existing installation kit so I saved a bit of $$.Installation was clean and fast and he took the time to walk through the features before I left. Highly recommend!!
I had a great time at this shop! The staff really knows their stuff and took the time to explain the different options without pressure. Installation was quick, clean and professional. Everything looks factory and sounds amazing. The prices were fair and customer service was above and beyond. I highly recommend this place if you're looking for quality car audio and excellent service.
Those guys are really professional! I had a new Alpine floating head unit installed in my 2008 Mercedes, and it feels like a brand-new car. The installation was super clean. At first, the sound wasn’t the same as the factory stereo, but Kevin tuned it to be just as good—if not better—without adding any new amps. They even used my factory GPS antenna so I don’t have extra wires hanging out. On top of that, they matched the online price. Big thanks to Kevin and Eddie—highly recommended!
Kevin was awesome, he took his time and explained everything to me. I went in initially for a dash cam install and then decided to get a sub and amp installed as well. Both turned out great and will be returning if I need more work done.
Came In not knowing what to expect when suddenly my stereo stopped working. Spoke with Kevin in the front and after a VERY fast diagnosing they discovered my wiring was incorrect. After only about 45 minutes total being in the store I was on my way to the beach with a working stereo again! Thank you so much SDCARSTEREO
Highly recommend Kevin and the team at San Diego Car Stereo for any issues with aftermarket stereos. I bought a car with an aftermarket stereo and AC unit that wasn’t working properly—specifically, the heat wasn’t functioning due to an improper setup. I had several people look at it with no luck, and even the dealership basically refused to help because it was an aftermarket install. I came to Kevin and his team over the holidays feeling pretty defeated, but he was confident he could get the heat working before I headed back to a Colorado winter. Sure enough, he got it done.
