About the Vibe OPTIFIESTA7-V9
From our tech experts at CEN
A vehicle-specific Vibe speaker upgrade for the Ford Fiesta and Ka, designed to fit the factory locations and connectors without cutting or fabrication, rated at 90w RMS.
Who it suits
Ford Fiesta and Ka owners who find the factory speakers the weak point. Vehicle-specific sets keep the work contained and reversible, which matters on a lease or a car you will sell on.
Our tech experts advise
Fitment varies by model year, trim and which factory audio system the car left with, so we confirm against your exact vehicle before ordering. These go further with an amplifier behind them. 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: Which vehicles does the OPTIFIESTA7-V9 fit?
A: It is designed for the Ford Fiesta from 2008 onwards and the Ford KA from 2008 onwards.
Q: What is included in the OPTIFIESTA7-V9 kit?
A: The kit includes a pair of OPTI6C speakers, a pair of VIBE wave diffusers, a pair of Anti VIBE sound deadening pieces, a pair of Ford speaker adapter brackets and a pair of Ford speaker adapter cables.
Q: What power does the OPTIFIESTA7-V9 handle?
A: The OPTI6C speakers are rated at 90 watts RMS and 270 watts peak, with 94dB sensitivity and a 4 ohm impedance. Vibe recommends the POWERBOX60.2-V7 amplifier.
