Model 3 RWD/SR+ 4-6 Speaker Unlock (2018–2023) On Site

***This upgrade is for combined labor when already on site for other services.***

Unlock the Full Sound System Your Tesla Already Has ⚡️

Early Tesla Model 3 SR+ and Rear-Wheel Drive vehicles came with all 6 premium audio speakers physically installed from the factory, but many were left disabled in software.

MaintainEV’s 4-6 Speaker Unlock Upgrade activates those dormant factory speakers, transforming your system into the full premium-style audio experience without adding aftermarket speaker hardware.

The result is noticeably fuller sound, improved clarity, stronger rear fill, and a much more immersive cabin experience while keeping everything OEM.
