Hello, I am wondering if anyone out there could provide a bit of guidance on some As-Built changes for an ACM from a 2018 Ford Fusion that I have put in to a 2014 Ford Fusion.
I originally had DS7T-19C107-BK in my Fusion and I swapped it with HS7T-19C107-ZD.
Everything seems to working fine options wise, but my issue stems with the ACM sending out high voltage through the speaker wires.
On the '14 original ACM, I changed to a flat variable output voltage and I was consistent voltage across test tones with max volume and unclipped.
I made (what I think are the correct changes) in the '18 ACM As-Built to do the same thing, but of the changes I’ve made so far, I now clip at various volume levels on different test tones (strongest tone I tested was 400Hz where it clipped at 22/30 volume) and my voltage output before clipping now is around 8V. I tried a couple changes in the As-Built, but no results yet for what I am seeking. Another thing I noticed too now is my rear speakers are rolling off the bass big time in higher volumes (fronts are not) and I believe I changed to a flat response as well, but obviously something is not right! I know there are some differences between the two ACM’s, but from what I was locating, it seemed that everything regarding speaker output was in the same build code lines.
I am sure there are others out there way smarter than I, that may be able help point me in the right direction!
Original As-Built data on the '18 ACM (in brackets is what I have changed it to for now) is:
727-01-01 - 1809 1808 0576 (185A 3800 01DB)
727-01-02 - 0100 0001 0033 (0033 0001 0065)
727-01-03 - 0000 0000 0032 (Same)
727-02-01 - 1344 (Same)
727-03-01 - 386A (Same)
727-04-01 - 0002 0143 41BA (Same)
I can certainly provide more details if needed.
