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 BMW 100 v2?
A: IS BMW 100 v2 woofers, T BMW inverted dome tweeters, tweeter brackets, tweeter crossovers, two 14 inch speaker leads with OEM harnesses on both ends, the user manual and an adhesive backed Focal Inside badge.
Q: How deep is the Focal IS BMW 100 v2 woofer?
A: The 4 inch woofer has a mounting depth of 1 inch (26mm), so it fits the shallow factory speaker locations in compatible BMW and Mini models.
Q: What is the difference between the Focal IS BMW 100 v2 and IS BMW 100K?
A: Both are 4 inch direct-fit component kits. The IS BMW 100 v2 uses a Polyglass cone and aluminium/magnesium tweeter at 40W RMS, while the premium IS BMW 100K uses Focal's K2 aramid fibre sandwich cone and TKM tweeter, rated at 60W RMS.
