Kenwood KFC-6988RS RS Series 6x9" 4-Way Coaxial Speakers
The Kenwood KFC-6988RS is a high-performance 6x9" 4-way coaxial speaker system designed to deliver crystal-clear audio and punchy bass for your vehicle. As part of the RS Series, these speakers feature an oversized 6x9" polypropylene woofer with a Diamond Array Pattern to minimize distortion and enhance sound clarity. With a low-profile tweeter design and multiple supertweeters, they provide a wide, immersive soundstage while fitting easily into most factory mounting locations.
Elite Performance Features
-
Diamond Array Pattern Woofer: This unique cone design increases structural rigidity to reduce distortion and provide a more accurate, punchy bass response.
-
Acoustic Sound Harmonizer: Strategically engineered to control sound waves from the woofer, ensuring they don't interfere with the higher frequencies for a smooth, natural tone.
-
Sound Field Enhancer: The specialized tweeter shape broadens the sound field in frequencies above 5kHz, creating a wider soundstage that fills your car’s cabin.
-
Factory Location Fit: The tweeter height is kept to a minimum (only 1/2" above the mounting plane), allowing these speakers to fit behind factory grilles in doors, dashes, or rear decks without modification.
-
Enhanced Heat Dissipation: A black-painted yoke and plate efficiently release heat from the magnetic circuit, protecting the voice coil and increasing long-term durability.
-
Optimized Woofer Damper: Features stress-leveling points that improve the mechanical life of the speaker while providing a smoother sound response.

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.
