CS Series 3.5" 2-way car speakers
The CS Series uses a heavy-duty motor and magnet structure with EVC™ (Extended Voice Coil) technology for precise linear excursion and ultra-clean bass — not found in stock speakers. Polypropylene cones and tough, ribbed, UV-treated foam surrounds deliver reliability even in heat and direct sunlight.
The stamped-steel framework keeps the build rigid, and the low-protrusion 3 mm tweeter design means these fit nearly any factory mounting depth. Recommended power is 30W RMS.

Our tech experts advise
Speaker sizes, adapter rings and harnesses vary by vehicle, year and trim, so we confirm what your car takes before ordering rather than guessing. Treating the door skin matters as much as the speaker: a good driver in an untreated door is doing half a job. 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: Where do 3.5 inch speakers like the Kicker 46CSC354 usually fit?
A: 3.5 inch speakers are commonly used in dashboards and some door locations. They need a 78 mm mounting hole and 48 mm of bottom mounting depth, so check these against your vehicle.
Q: How much power do the 46CSC354 speakers need?
A: Kicker recommends 30W RMS per speaker, with peak handling of 90W.
Q: Are grilles included with the 46CSC354?
A: No. Grilles are not included with this model.
