ForScan Flat EQ before key200.4?

[colinl]

the filter is 300hz which certainly would have a big impact even if you have an amp or loc with integrated dsp.

googling I see other Ford models like F-150 and Bronco are having this issue also. I suspect it can't be disabled on a 24 like a 22 accept.

the front doors are electronically crossed at like 80-90hz. I didn't know if flat eq affects them.

Wondering if after I tap the front speakers for the signal to the sub amp if I should disconnect the rear speakers from the amp.

Yes, set to All Seats Occupied

With Forscan set to "flat EQ" the "All seats" and "Driver seat" are identical--no difference in response or speaker levels.

There could be a lot of reasons for this really. I am pulling my signal from the fronts, fwiw. What sub/enclosure do you have?

Doesn't matter which XL or XLT speaker circuit(s) you tap for the sub, when you set Forscan to "flat EQ". The rear speakers are a far EASIER place to tap.

So to be clear with what you're saying is regardless of if I tap the rears or the fronts or both the front and the rears the signal is being sent the same to all speakers when forescan is set to flat EQ and all seats occupied is also set?

Is that what you're saying?

It does. The electrical response is not longer steeply rolled off at 60Hz to ALL speakers circuits when "flat EQ" is employed.

It isn't hard to get to, and running a couple of speaker wires should be pretty painless. It'll just take a little time to route the wires around. If you plan on doing more later, I'd highly recommend getting the PAC T-harness from Crutchfield. It'll make life so much easier, and you won't have to cut a single factory wire.

If I were to get this and have it feed to an aftermarket DSP to an Aftermarket 5 channel amp, would if then make sense to run aftermarket wire from that amp to the Fronts/Rear or somehow reuse the factory wiring?

I think for now I'm just going to leave it as is with my signal coming from the rear speakers. It's just weird to me how some songs sound great with the kick drums the bass guitar, everything just sounds perfect.

Then a different song sounds okayish, then another song just sounds like trash with horrible bass response if any. I don't know if my expectations are just too high and it's just Ford's doing with the head unit and the EQ of the Maverick.

I just hate jumping further down the rabbit hole spending more money and time running wires buying a harness like the pac lock pro to get my signal from the front speakers as well. Only to find out it didn't make any bit of difference and the bass output is still the same.

If there was a guarantee that running the signal from my front speakers off the head unit would make a improvement in the bass output of my sub I would happily get the lock pro harness and run wires from the front speakers to my amp for the signal. But after speaking to two advisors at crutchfield they pretty much were thinking like me that there's not much if any improvement going to be gained by buying the loc pro harness and running the signal from the front speakers, The outcome will most likely be the same.

Yes, "flat EQ" removes ALL electrical LF rolloff, and the 70Hz LF boost, HF boost and other small EQ, to ALL 4 speaker circuits for XL/XLT audio units.

interesting that you didn't include or otherwise comment on my statement in this quoted post that some people are noticing no different with flat eq.

it's either that a lot of people are unable to use Forscan properly, or the ACM does not accept flat eq on newer trucks. the value is accepted, no checksum error, but it doesn't change the electronic crossover setting.

Crutchfield is wrong IMHO.

There is not a single person complaining of bass output tapped on the front door outputs.

Conversely, many have complained of bass output tapped on the rear pillar outputs. Some, but not all, people have reported improvement with flat eq and other Forscan tweaks.

Yeah, as I've stated before I tapped the rear speakers for the signal to my amp which also will power on as well as shut my amp off when no signal is being sent so there's no need for a trigger wire. But I do have my EQ set to flat via forscan as well as all seats occupied not driver.

I wound up just now adjusting the LP Filter on my amp down from 100 hz that I had it set at, down to 70 hz. Which has so far seemed to get rid of the annoying midbass response in my sub, and allowed me to get a little better low frequency response. Without having so much muddy mids mixed into the subs output.

I'm hoping that having the low pass filter set too high was what was given me the bad bass output response.

dumb question, but is your sub out of phase with the door mids? it would take a few seconds to swap the terminals to check.

I took my time when splicing the rear metra connectors to tap the rear speaker signal for my sub amp. I'm not saying it's out of the realm of possibility I am human. Sadly verifying 100% requires me ripping the rear panels off the speakers to check, as I've also wondered if maybe one is wired out of phase.

As I wrapped all my wiring with Tessa tape.
