About the UP X4BMW-FRT.1
The factory speaker setup in many BMW vehicles falls short for serious listeners. The Match UPGRADE range offers a direct, vehicle-specific replacement. The UP X4BMW-FRT.1 uses car-specific baskets for a straightforward, clean installation, and the 13 mm silk dome tweeter delivers improved treble resolution over the standard fit.
Paired with a DSP amplifier — such as the BMW-specific Match UP 7BMW — these speakers perform at their best.

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: Which BMW models does the UP X4BMW-FRT.1 fit?
A: It is listed for BMW 1, 2, 3, 4, 5, 6 and 7 Series, i3, i8, X1 to X6 and Z4, plus Mini R60, R61, F54, F55, F56 and F57. Because there are FRT.1, FRT.2 and FRT.3 versions, add your model, year and speaker position at checkout or contact CEN to confirm.
Q: Do the UP X4BMW-FRT.1 speakers work with the factory radio?
A: Yes. Inline crossovers are included for use with the OE radio, and they can also be combined with a MATCH DSP amplifier such as the BMW-specific UP 7BMW.
Q: What's in the box with the UP X4BMW-FRT.1?
A: Two coaxial speakers, two inline crossovers and the instruction manual.
