JL Audio C3-650 | C3 Series 6.5" Convertible Component System
The JL Audio C3-650 (Part Number: 010-03172-00) is an incredibly versatile system designed for enthusiasts who want premium performance without being locked into a specific mounting style. Known as a "Convertible" system, it can be deployed as a true component set with separate woofers and tweeters, or as a high-end coaxial by mounting the tweeter directly onto the woofer's pole piece. This flexibility makes it the perfect problem-solver for vehicles with difficult factory locations.
Product Highlights
-
Convertible Versatility: Whether you need a separate woofer and tweeter for a better soundstage or a space-saving coaxial setup, the C3-650 handles both. Switching between configurations takes only a few seconds using the included phase plugs and tweeter mounts.
-
Pure Silk Dome Tweeters: The 1-inch (25 mm) silk dome tweeters deliver a smooth, natural high-frequency response. Silk is chosen for its inherent damping properties, which eliminate the "harshness" often associated with metal dome tweeters.
-
DMA-Optimized Bass: The woofers utilize JL Audio’s proprietary Dynamic Motor Analysis (DMA) to ensure the motor remains linear under high power. This results in tight, articulate mid-bass that remains clean even during aggressive musical passages.
-
Elevated Frame Cooling: The woofer basket design incorporates patented cooling technology that pumps air directly over the voice coil. This prevents thermal compression and ensures the speakers sound just as good at the end of a long drive as they did at the start.
Key Features
-
Premium Outboard Crossovers: This system includes a true two-way passive crossover network featuring midrange compensation and a 4-position tweeter level control. This allows you to calibrate the brightness of the system based on your interior acoustics.
-
Long-Excursion Design: Featuring oversized 1.2-inch voice coils, these woofers are built for high output. The long-excursion capability allows them to move more air, providing a richer, more impactful low-end than standard factory replacements.
-
Mineral-Filled Polypropylene Cone: The woofer cone is mineral-filled for added stiffness and durability, ensuring accurate reproduction of mid-range frequencies and vocals.
-
Flexible Fitment: The system includes multi-application adaptor rings, making it compatible with a wide variety of 6.5-inch and 6.75-inch factory locations.

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.
