Android Auto won't give me an equalizer, so I use this free app instead

Android Auto lacks a built-in equalizer, which is a problem for audiophiles who want optimized car audio. The solution is to use a system-wide equalizer app instead of relying on per-app EQ settings. Poweramp Equalizer is recommended as a paid option that automatically switches profiles based on the connected audio device. For a free alternative, Wavelet offers similar system-wide equalization with headphone presets and customizable EQ curves. Both apps require enabling specific permissions (Legacy Mode and DUMP/ADB permissions) to work properly with Android Auto.
