Model 3 SR+ 6-Speaker Hardware Activation (2018–March 2020)

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 some speakers were not active in the original configuration.

MaintainEV’s 6-Speaker Hardware Activation 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 retaining the factory speakers and appearance.

This is a hardware-based upgrade; no software unlocking is performed.

What’s Included

✅ Activation of 6 factory-installed dormant speakers

✅ Hardware-based speaker activation and testing
