Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Speed-dependent equalizing
In conjunction with the Top Hi-Fi amplifier (AMPT) optional equipment, the headunit provides the 7-band equalizing function. Depending on the speed signal, the volume of a set tone frequency range is increased in order to counteract noise caused by the vehicle acoustics when the vehicle is in motion. Adaptation is mainly performed in the low audio frequency range.
