The GLADEN SoundUp TE-3SR-Basic-Sub is a plug-and-play sound upgrade designed specifically for Tesla Model 3 and Model Y vehicles with a standard SR audio system. It is designed for drivers who want to improve their vehicle's sound with more bass and dynamics without interfering with the technology.

The system is based on an integrated concept that complements the standard audio system by adding an additional subwoofer. This significantly improves sound reproduction in terms of pressure, volume, and balance, rendering voices and instruments more clearly and with greater control.

The integration process is completely plug-and-play and tailored to the Tesla-specific audio architecture of the SR models. The original wiring harness remains intact, and installation is straightforward, reversible, and gentle on the vehicle.

The SoundUp TE-3SR Basic Sub offers an efficient sound upgrade that preserves the original equipment manufacturer (OEM) character of the vehicle, specifically enhancing the sound in the low frequency range where it is most noticeable in everyday use.
