① Extract 4 speaker signals: You can easily extract 4 speaker signals (front left/right and rear left/right) from your factory navigation/car audio system.
② Power can be drawn from all sources at once. Since constant power, ACC power, and ground can be drawn from all sources simultaneously, wiring to additional equipment such as subwoofers and tweeters can be done smoothly.
③ Easy installation with coupler connection: The coupler design simply connects to the Honda 24-pin connector (with locking pin, Type A). No cutting or modification of vehicle wiring is required.
④ Does not damage the original wiring. Since no wiring modifications are made, the burden on the vehicle is minimized, and it is possible to return to the original state by removing it.
⑤ Supports a wide range of audio customizations: Can be to add various car audio equipment such as subwoofers, tweeters, and line converters.
