About the Vibe OPTITESLA1T-V4
From our tech experts at CEN
A vehicle-specific Vibe speaker upgrade for the Tesla Model 3, designed to fit the factory locations and connectors without cutting or fabrication, rated at 40w RMS.
Who it suits
Tesla Model 3 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: Is the OPTITESLA1T-V4 plug and play?
A: Yes. It bolts directly into the factory mounting locations and uses the factory plugs and looms, so no modification is needed.
Q: What is the frequency response of the OPTITESLA1T-V4?
A: 4.5kHz to 25kHz, with 92dB sensitivity and a 4 ohm impedance.
