Our tech experts advise
Sizes, adapter rings and harnesses vary by vehicle, year and trim, so we confirm what your car takes before ordering. Door treatment matters as much as the speaker. 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: Do I need to cut or modify my car to fit this kit?
A: No. The OPTISOUND kit includes VW specific adapter brackets and adapter cables so the speakers fit the factory locations and plug into the factory wiring.
Q: What is in the OPTIVWKT-V8 kit?
A: 1 pair of OPTI6C speakers, 1 pair of VIBE wave diffusers, 1 pair of Anti VIBE sound deadening pads, 2 pairs of VW speaker adapter brackets, 2 pairs of VW speaker adapter cables and 1 pair of tweeter fittings.
Q: Does the OPTIVWKT-V8 fit Seat and Skoda models?
A: Yes. As well as VW models such as the Golf, Caddy, Touran and Tiguan, it is listed for the Audi Q3 and several Seat and Skoda models. Check the full list in the Specification tab.
