Our tech experts advise
At 2 ohms impedance, check your head unit or amplifier supports this before fitting. The kit requires tweeter slots in the door trim, so verify your variant has them. Compatibility covers many recent Volkswagen, Seat and Skoda models — contact us to confirm your year and trim. Installation is priced per vehicle; see our car audio fitting service for details.

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 cars does the Focal IS VW 155 fit?
A: It is designed for the latest Volkswagen models such as the Passat, Tiguan and Golf 8, and can also be installed in many Seat and Skoda models. The car must have tweeter slots. Contact CEN with your registration to confirm fitment.
Q: Do I need to cut any wires to fit the IS VW 155?
A: No. The kit uses vehicle-specific connectors and a chassis-integrated spacer, so it fits the original locations with no cutting or modification and no additional accessories.
Q: What is the impedance and power handling of the IS VW 155?
A: The kit is 2 ohms, handles 50 W RMS (100 W peak) and has a sensitivity of 92 dB.
