We asked Audio Technica to develop an original cable that was cheaper but of higher quality specifically for the plan after repeated tests.
Use this cable to reroute the cable from the deck to the network and then to the speakers. As for the length, add only the amount you need depending on your car. (Store construction)
The reason why we decided to produce original cables is because there were cases where cables that cost less than 100 yen cost tens of thousands of yen even though they were only used for a short time. I made an original speaker cable. By the way, the superior cable to this cable is Audio-Technica's AT-RS160.
