Does anyone know how to silence the sound of the Ocelot Jugular car for pure mode

Does anyone know how to mute the sound on an Ocelot Jugular car stereo in pure mode without it crashing and giving errors? I just mute the sound, I don't change the volume or the Hz, I just remove the sound, put it back in AWC and try in OpenIV, but it still gives an error without changing anything.
