Convertible EQ/DSP change when unlatching the top

[Hilfloskind]

Question (also posted in the massive infotainment thread about speaker and stereo information):

I am getting ready to install my Orion 12" sub and amp in my 2018 convertible (need a custom fab box made) to replace the pathetic sub that comes with the Shaker Pro system. When I do this, I am also planning to upgrade the door 6" and 3.5" speakers to Powerbass woofers and Infinity reference coax 3.5"s (already swapped the center channel for this one and want to match it with the door 3.5"s).

My question is this: when I use FORScan to flatten the EQ, will this also remove the weird bass reduction/DSP effect that occurs when you unlatch the top? On the convertibles, when you drop the top it changes the audio profile and reduces the bass output fairly significantly. I definitely would like to deactivate this setting as well, but I'm not sure if the EQ flattening setting also covers this change. Anyone know?

Thanks!

Hi, did you get any reply or answer on this regard? I have added sub and amp, and replaced the rear speakers and would like to confirm on this.

Cheers!

I am looking for answers on this too

I was able to disable the unlatch EQ change through Forscan.

It still mutes for a second but the audio stays the same as with the top up.

783-01-01: 2000 AC to 0000 AC

Awesome find. Now I have to figure out how to program that.

Wonder why Ford did this anyway.

Nice, I'll try this out this weekend! And report back

Damn! I had no idea there was an auto adjustment on bass output for when tops are down. God bless Ford for being so thoughtful to help Mustang owners reduce noise pollution. I'll need to invest in the FORscan software to disable so that I can get the most of my aftermarket subwoofer. BTW, I didn't know that the Shaker was available for the convertible. Also, I'm hearing from many that disconnecting the center speaker makes an instant improvement to the sound system. I wonder if it makes any sense to upgrade the rear speakers or are they installed just to claim a higher speaker count number?

Hi Gents, so I tried this and to be very honest I could not hear that much of a difference. That could be because I have already flatten the EQ, maybe.

Nevertheless, is not like nothing else got disrupted either.

Same as ecerdas. I have a 2018 convertible GT, 9 speaker system, and hear no difference between when the top is latched and unlatched. And I didn’t change any of the Forscan settings. I must have gotten lucky.

It seems to cut the very low bass and maybe compensate by putting a bump in higher in the range (haven't taken the time to do an RTA on it). You need to have the right song to hear the difference. It might not be as noticeable without an aftermarket sub.

Tag.

Anyone know the line to edit to flatten the EQ as well?

Hello Guys,

I'm trying to modify the line 783-01-01: 2000 AC to 0000 AC in Forscan but I' don't find it?
Can you please tell me in which module I can find it (ACM ? PCM ?.....)

Thanks

My B&O system sounds better with the top down. I figured all that padding on the top was absorbing some sound.

Were you able to find it? I haven't found it either.
