The GLADEN SoundUp TE-3Prem-Basic-Sub is a plug-and-play sound upgrade designed specifically for the Tesla Model 3 with a standard premium audio system. It is designed for drivers who want to expand and enhance the low-frequency sound of their vehicle 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 noticeably improves the foundation, pressure, and control of low-frequency sound reproduction while retaining the clarity and detail resolution of the existing premium system.

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

Thus, the SoundUp TE-3Prem-Basic-Sub offers an efficient sound upgrade that preserves the original equipment manufacturer (OEM) character of the vehicle while enhancing the sound in the low-frequency range, where even the standard premium system reaches its limits.
