Will the factory screen and steering controls still work?

Yes. Everything integrates with the original system, so the display, steering controls and chimes work exactly as before.

No. We work within the factory apertures and mounting points, so the install is fully reversible and the interior looks untouched.

Do I need to replace the factory amplifier?

No. Our upgraded mids and tweeters deliver more definition through the factory amp. Amplification and processing are available if you want to go further.

Can this be done alongside other work?

Often, yes. If your car is with us for service or interior work, combining jobs saves labor because the trim is already out.

The Sound A McLaren Should Have Come With

When it comes to the factory McLaren speaker system, there is a lot of room for improvement. Our upgrade delivers stronger mid range presence, richer low end, and cleaner highs that cut through without distortion. You get fuller detail, better imaging, and a balanced stage that transforms every drive. This is the sound a McLaren should have come with.
