Hertz K 165 | Uno Series 6.5" 2-Way Component System
The Hertz K 165 is a high-efficiency 165 mm (6.5") component system designed to deliver the "Hertz Sound Experience" as a direct replacement for basic factory speakers. Like its larger sibling (the K 170), the K 165 focuses on providing a brilliant and detailed high-frequency response while remaining incredibly easy to install. It is the ideal entry point for listeners who want clear, dynamic audio without the need for high-powered external amplification.
Product Highlights
-
Neodymium PEI Tweeter: The 24 mm (0.9") tweeter uses a PEI dome for crystal-clear highs. Its compact size and annular acoustic lens are optimized for exceptional off-axis performance, ensuring a realistic stereo image even in difficult factory mounting spots.
-
V-cone® Technology: The woofer features a pressed-paper cone with a water-repellent treatment. The V-cone profile improves dispersion and provides a solid, punchy bass response that brings energy to your music.
-
High Sensitivity: With a rating of 93.5 dB, these speakers are among the most efficient in their class, making them perfect for boosting the volume and clarity of a standard factory head unit.
-
Integrated Crossovers: The 6dB/Oct crossover is built directly into the tweeter wiring. This "hidden" design saves space and simplifies installation, as you don't have to find a place to mount a separate crossover box.
Key Features
-
Foam Surround: The woofer utilizes a high-damping foam surround that balances sensitivity with control, allowing for high SPL (Sound Pressure Level) and reliable performance.
-
High-Flux Ferrite Magnet: Driven by a powerful motor assembly, the 25 mm (1") voice coil provides the dynamic power handling needed for clean, undistorted sound at higher volumes.
-
Compact Mounting: Designed with a slim profile to fit the majority of 6.5-inch factory locations, reducing the need for custom baffles or modifications.
-
Reliable Build: The woofer basket is protected by a resistant coating, ensuring the speakers withstand the vibrations and temperature changes common in a car door.

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.
