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's in the box with the Focal IS MBZ 100?
A: Two IS MBZ 100 woofers, two TMBZ tweeters, 2 crossovers, 2 woofer protection circuits, 2 Focal Inside badges and a Focal window sticker.
Q: What is the difference between the Focal IS MBZ 100 and IC MBZ 100?
A: The IS MBZ 100 is a component kit with separate tweeters for Mercedes models that have tweeter locations, rated at 50W RMS. The IC MBZ 100 is a coaxial with the tweeter built in, for models without tweeter locations.
Q: Do I need to cut wires to fit the Focal IS MBZ 100?
A: No. It uses Mercedes-specific wire connectors and a dedicated plug and play connector, so no wire cutting or vehicle modification is needed.
