EZGO TXT Bluetooth Dash Speaker System

Turn an unused dash opening into a clean, integrated Bluetooth audio system.

This project was designed around an E-Z-GO TXT golf cart after relocating the factory battery gauge and USB charger, leaving two unused openings in the dashboard. Rather than installing a traditional head unit, I designed a compact Bluetooth speaker system that fills the opening while providing surprisingly good sound from inexpensive off-the-shelf components.

The system uses dual full-range speakers housed in sealed enclosures with a hidden Bluetooth amplifier mounted behind the dash. The result is a simple, low-profile audio upgrade that looks right at home in the cart.
