Hertz Cento CP 1.700 Monoblock Class-D Amplifier
Product Overview:
The Hertz CP 1.700 is a high-performance mono amplifier from the Cento Power series, engineered to deliver substantial power in a compact footprint. Utilizing Advanced D-Class (ADC) technology, it achieves over 89% efficiency, making it a reliable choice for both traditional and electric vehicles. This amplifier is specifically designed to drive subwoofers with authority while providing a high degree of signal purity and tuning flexibility.
Key Features
Advanced Class-D Efficiency
The CP 1.700 is built with an Advanced D-Class (ADC) output stage that minimizes heat generation and power consumption without sacrificing output. This high efficiency allows it to deliver a consistent 700W RMS @ 2Ω, providing the necessary impact for high-excursion subwoofers while remaining stable in tight installation spaces.
Precision Tuning & Customization
This amplifier puts professional-grade sound control at your fingertips with top-panel accessible adjustments. It features a variable phase control (0-180°), which is essential for perfectly time-aligning your subwoofer with your front speakers. Additionally, it includes a 24dB/Oct. low-pass filter, a subsonic filter, and an adjustable bass boost (0-9dB @ 50Hz) to tailor the low-end response to your vehicle's acoustics.
Universal Compatibility & EV Readiness
Equipped with a Universal Speaker Simulator (USS), the CP 1.700 can be integrated with modern OEM head units that feature "speaker load detection." Its wide operating voltage range (9V to 18V) ensures it functions optimally in electric vehicles (EVs) where voltage fluctuations can be common.
Audiophile-Grade Signal Path
To ensure your bass stays clean and free from interference, Hertz utilized balanced input circuitry for both the Pre-In and Speaker-In connections. This design offers high-noise rejection, protecting the audio signal from electronic "hum" often found in vehicle environments. It also includes a full-range pre-out, allowing you to easily chain additional amplifiers for more complex system expansions.

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.
