Then firmly press each of them to secure the panel to the door. A click is audible when the clips are inserted correctly.
The importance of speakers in car audio systems is even greater. For car speakers to present excellent sound and sense of positioning, compared to home audio, the technical requirements and difficulties are much greater. The disadvantages of car speakers are numerous and complex, as there are some disadvantages that are not available in the interior space of the car: narrow spaces, uneven objects, complex environments (noise, vibration, vehicle materials, etc.) and the installation position of the speaker (limited by the interior and exterior of the car); more importantly, the listening position is not good, left and right; And since the direction of the speaker is not equal and symmetrical, it leads to complicated frequencies, phase differences and peaks, valleys, standing waves, reflective time difference, long reverberation time (resonance), etc., are not conducive to hearing problems.
In addition, due to the different amplification and power requirements of different units, car audio can usually only use multiple amplifiers to drive the speakers (many models need to be amplified by multiple amplifiers for low-frequency parts), so it is difficult to achieve an optimal level of tonal balance.
