About the JL Audio C2-350X
From our tech experts at CEN
JL Audio C2 Series 3.5 inch coaxial speakers, with the tweeter mounted in the centre of the woofer, rated at 25w RMS.
Who it suits
Drivers replacing tired factory speakers who want a clear improvement without relocating tweeters. C2 adds noticeably more detail and output for a modest step up.
Our tech experts advise
Sizes, adapter rings and harnesses vary by vehicle, year and trim, so we confirm what your car takes before ordering. Door treatment matters as much as the speaker, and JL drivers repay an amplifier. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: How deep is the JL Audio C2-350x?
A: The mounting depth is 38 mm and the mounting hole diameter is 81 mm. The tweeter protrudes 14 mm from the mounting surface.
Q: Are grilles available for the C2-350x?
A: No. Speaker grilles are not available for this system; the low tweeter protrusion is designed to fit behind most factory grilles.
Q: What's in the box with the C2-350x?
A: Two 3.5 inch 2-way speakers, four #8 x 1 inch self-tapping screws, four speed clips, two 0.205 inch (5.2 mm) and two 0.11 inch (2.8 mm) crimpable female quick slides, and an owner's manual.
