About the Focal IS T3Y 100
From our tech experts at CEN
The Focal IS T3Y 100 is a 2-way component kit from Focal's Inside Series, designed as a direct-fit replacement for the front speakers in the Tesla Model 3 and Model Y. It uses a 4" (100mm) Flax cone midrange driver and an aluminium inverted dome tweeter, with 50W RMS (100W max) power handling. The kit is fully plug-and-play with no vehicle modifications required.
Who it suits
Tesla Model 3 and Model Y drivers who want improved audio clarity without cutting or permanent wiring changes will find this a practical choice. The kit covers the front channels only; for extended bass, pair it with Focal's IW T3Y 200 8" woofer kit. Browse the Focal collection for other vehicle-specific options.
Our tech experts advise
At 4 ohms and 87dB sensitivity, this kit runs from the Tesla's standard head unit without an additional amplifier, though adding one will improve dynamic range. The 33.8mm mounting depth is sized for Tesla door cavities. Professional fitting is priced per vehicle — see our Nottingham car audio installation page 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 Tesla models does the IS T3Y 100 fit?
A: It is designed for the Tesla Model 3 and Model Y and fits as a plug and play upgrade with no vehicle modifications.
Q: Which speakers does the IS T3Y 100 replace?
A: It upgrades the front channels with a 4 inch (100mm) Flax cone midrange and an aluminium inverted dome tweeter per side.
Q: What power does the IS T3Y 100 handle?
A: Each kit handles 50W RMS (100W max) at 4 ohms, with a sensitivity of 87dB (2.83V/1m) and a frequency response of 150Hz to 20kHz.
