Looking for an easy upgrade to your factory audio? The JL Audio C2-350x car speaker is your go-to choice for crisp, compact sound. These 3.5-inch coaxial speakers deliver detailed highs and mids, breathing new life into your car stereo without taking up space.
Perfect for dash or rear speaker locations, the C2-350x proves that small size doesn’t mean small sound. Whether you're commuting or cruising, enjoy richer vocals and more natural tones in every track.
The C2-350x car speaker may be one of JL Audio’s smallest speakers, but it packs a punch. Designed for tight spaces, this full-range speaker delivers smooth mids and defined highs. It’s a quick way to dramatically enhance clarity over stock systems.
Thanks to its 0.75" silk dome tweeter, highs are clean without being sharp. The mineral-filled polypropylene cone ensures warm midrange tones, perfect for vocals and instruments.

0.75-inch silk dome tweeter
Built-in crossover network
Power handling: 20 watts RMS (105 watts peak)
Frequency response: 100 Hz – 22,000 Hz

Ideal for dash and tight-space installations
These specs make the C2-350x car speaker ideal for modern compact vehicles or older models with limited mounting options.
Installing the C2-350x is a breeze. It fits into most factory 3.5-inch speaker locations without modification. Whether you’re replacing dash speakers or adding to a custom setup, it’s an easy plug-and-play upgrade.
The shallow depth ensures it clears obstructions behind the mounting location. That’s especially helpful for newer car models with tighter tolerances.

A built-in crossover in each speaker directs highs to the tweeter and mids to the woofer. This separation prevents distortion and keeps your audio crisp. It works seamlessly with stock or aftermarket head units.
This design also avoids the hassle of external crossovers, simplifying installation and wiring.
JL Audio uses only durable, moisture-resistant materials. The polypropylene cone resists heat and humidity inside your car. The silk dome tweeter withstands vibrations and extreme temperatures. Expect consistent, long-lasting performance.
Whether you're replacing aging factory units or starting a full audio overhaul, these speakers are built to endure.
High temperatures and UV rays can damage your car's audio system over time. Car window tinting helps keep your vehicle cool and comfortable.
Tinted windows protect your speakers, electronics, and upholstery. They reduce glare, improve listening environments, and even increase audio clarity by lowering cabin echo.
At Audio Jam, we don’t just sell speakers—we install and optimize them. Our expert technicians ensure your C2-350x speakers are securely mounted and properly powered. We tune the sound for your specific vehicle.
From speaker upgrades to full sound system builds, we handle it all with precision.
