JL Audio C3-650cw | 6.5-inch (165 mm) Component Woofer
The JL Audio C3-650cw is a high-performance 6.5-inch woofer that serves as the backbone of a premium audio system. Engineered for maximum versatility, this driver can be used as a dedicated woofer in a component system or converted into a coaxial speaker with the addition of a C3 tweeter. It features JL Audio’s most advanced cooling and motor technologies to deliver punchy mid-bass and crisp midrange with minimal distortion.
Product Highlights
-
Convertible Design: Offers the flexibility to be installed as a separate component woofer or transformed into a coaxial configuration for tighter spaces.
-
DMA-Optimized Motor: Utilizes Dynamic Motor Analysis to maintain a stable magnetic field during high excursion, resulting in significantly cleaner and more accurate bass response.
-
Elevated Frame Cooling: This patented design allows air to flow directly over the voice coil, significantly improving power handling and reducing thermal compression during long listening sessions.
-
Glass-Filled Polymer Basket: A non-resonant, non-magnetic frame that ensures the motor’s energy is focused entirely on the cone for maximum efficiency.
Key Features
-
Mineral-Filled Polypropylene Cone: Provides the ideal balance of stiffness and damping for a natural, uncolored sound across the frequency spectrum.
-
Large 1.2-inch Voice Coil: Substantially larger than standard 6.5-inch drivers, allowing for higher power handling and better control over the woofer's movement.
-
Progressive-Roll Spider: Precisely controls the cone's movement at high volumes, preventing mechanical noise and ensuring linear travel.
-
High-Excursion Capability: Designed to move more air than traditional speakers, providing the "thump" you expect from a premium JL Audio component.

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.
