Hi All, Sorry for replying an old post, but I found this tread via Google when I was looking for a setup to Match 5.4 DSP amp. I have Octavia 4 sedan 2022 with a OEM basic (columbus?) sound system, stock speakers. I installed a Match 5.4DSP and Match PPQ8 subwoofer plus URC3. 12V directly from the battery so using High power mode. I got the sound, all is working well but to be honest, I have no idea how to set all the things like they should be… Music doesn’t sound terrible, but still thinking is there something I’m missing. So the question. Does anyone have an .afpx-file to share for good/nice settings to the Octavia 4 for the same Match + Sub configuration? I will try some tricks told in this tread but learning will take forever... Thanks for the help. -T
