3. Configuració Amplifier Gains: Carefully adjust your amplifier's gain settings to match the output of your head unit. Avoid setting the gain too high, which can lead to clipping and damage to the midwoofer.
4. Configuració de crossover: Utilitza el teu amplifier's or head unit's crossover functions to properly filter frequencies. For the VO-W712-D2, a low-pass filter (LPF) is typically used to prevent it from playing frequencies too high, while a high-pass filter (HPF) might be used on other speakers to prevent them from playing frequencies too low. Refer to the specifications for recommended frequency response.
