Yep did the Forscan change this weekend and can’t tell the difference, was hoping for a more noticable improvement. My two complaints with the stock base system are not enough volume or bass. Don’t know what the sensitivity of the stock speakers is, but 92.5 dB for these Kickers should produce a noticable increase in output volume. The speaker construction isn’t the usual coated paper with silk tweeter so was hoping someone could confirm a good sound with the improved bass and volume.
Every time I've done it, there has been a very noticeable improvement in sound especially in the bass, above 16 the bass would roll off and the highs were ear piercing, after forscan the highs were way more pleasant and the bass remained strong all the way to max volume. Maybe my ears are just more sensitive but the doctor's say I have a 30% hearing loss. Go figure, everyone is different no doubt.
The bass is definitely volume dependent, but the over accentuation of treble the factory eq's in is not. Removal of the ear piercing highs was a massive improvement throughout for me.
So you put in another 6.5 woofer and a 3.5 coax with the stock amp and were happy with it? What speakers did you use? Do you have a sub?
Are you able to tell me what exact Forscan changes you made? Wondering if I did it wrong.
That's exactly what I did. I had a set of Rockford fosgate separates, i used the woofer and left the tweeter out as they are a little too bright for my taste. I used a set of Kenwood 3.5 Coax for the mid tweeter combo. Used the supplied bass blockers that came with them. The results were outstanding. The fosgate woofers being powered by the factory dsp/amp put out phenomenal bass for not having a sub the bass is really strong in my wife's Ecoboost premium. Also disconnected the a pillar tweeters. Fosgate prime 1675s were the 6.5, Kenwood kfc-x3c are the mids I used. I do plan to also replace the rear deck speakers with fosgate 3 ways that I have.
I changed 727-01-02. 01xx to 727-01-02. 00xx that is the only change I've made for the acm.
Just checked in Forscan and I may have screwed something up...it currently reads 0088 B9 and I think I may have accidentally deleted 2 characters in the "B9" section. Seems like there should be 4 characters there. Any chance you could tell me what your exact 727-01-02 entry is with all 8 digits? If not no problem, I know it's a pain.
I would suggest you download your as-built data from Motorcraft. You can find all your original values there. https://www.motorcraftservice.com/AsBuilt
I added Sync 3 myself and the APIM was from a Fusion I believe so wonder if that would work?
I did back up the file before changing 727-01-02 but couldn’t reload it for some reason ugh.
Ok. Then you're F'd...
