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: What is the mounting depth of the Phoenix Gold Z4CXi?
A: The Z4CXi needs 43mm (1-11/16 inch) of mounting depth and a 103mm (4-1/16 inch) mounting diameter.
Q: What power do the Z4CXi speakers handle?
A: They are rated at 30W RMS and 120W peak, at 4 ohms with 86dB sensitivity.
Q: What comes in the box with the Z4CXi?
A: The box contains 2 coaxial speakers, 2 speaker grilles, a mounting template, 8 mounting screws and a user manual.
