not sure.
The link above is from Metra’s LOC DSP. It’s been designed for gen-9 Accord but it has been used on gen-10 ACCORD with slight modifications.
However, all the sample video have been on 8-speaker systems that do not have their tweeters actively crossed inside the amp. I’m just wondering if those outs have the wires on that harnes that can be tapped for signal or are they just absent from the harness?
