In fact, Civic's original car audio still feels that it is OK, because the high tone and heavy bass sound field of the original car audio are clearer, compared to other original car audio turbidity, slightly clearer boundaries, but if the requirements are relatively high for the owner, the acoustic effect of the original car can not be satisfied.
The original car horn has no crossover, only the midrange and tweeter, and the modified Decaonic speaker adds a crossover, and uses the crossover to separate the signal to the midrange speaker and the tweeter, making a more detailed distinction.
The delicate and weighty JCDecaux speakers are perfectly made and the sound quality is extraordinary.
We can see that the rear door Civic does not have a horn, but there is a large gap in the door panel, so we must do a layer of professional sound insulation to seal the gap to avoid the entry of noise.
Civic rear sound field horn is in the rear panel position of the tail box, so we install the horn here to achieve the principle of consistency with the original car horn.
Honda Civic's treble was mounted on the door panel, installed in the original position, all non-destructive modifications, but we made a layer of glue in the outer ring to fully fix the horn and not let the horn move.
