FORScan Mustang Audio EQ fix - Disable Factory EQ for Full Sound Range 

Thanks so much for the kind words, glad you enjoyed the video!

Really glad it worked for you!

Does this take bass roll off out

@@joshunger8922 worked on wife’s eco boost. Also took out the pumped in engine noise. Actually this did not work on my 2019 GT with the 9 speaker analog system. The option was not available in forescan! I could have used a DSR1 and cut into harness, but I decided to replace radio with Alpine halo I’ll 9. I used an idata RR and have now built an expensive SQ system in it.

I have 21 eco with 9 speaker I added a amp and subwoofer and when turn It up to lime volume 19 the bass goes away

I agree with you 100%. I still need to do the rear speakers too, and definitely needs a sub. But the difference was night and day better than where it was. Glad it worked for you!

@@RaymondLambHi. I heard in the forscan forms that this has screwed a few people up. Making the radio pop and shut on and off without being able to fix. Not sure if someone just put the wrong numbers or whatever. Have you guys heard of anything unusual? Because I was gonna try this to my 2017 F150 after installing four new speakers myself. Do you guys have any information I would appreciate it. Thanks man

Hey Joe, I personally haven't experienced any issues. It may come down to the wrong value being used, like you said. There is a way with the software to backup the asbuilt data before you do anything and then you could restore it if something went wrong and it "should" set it back to original. I haven't done it myself, so not much help there. I'd research the backup option and make sure you are good there before doing anything. There is also a way to download the asbuilt file from Ford too if you search for it and use the VIN number. I'd just try to make sure you have the correct value for your specific setup. Good luck with it!!

@@RaymondLambThanks for replying man. Where did you find these numbers to get to begin with? I used foreskin on a few things that work very well and I’d like to try this one. Just don’t know where the actual find the numbers

I was lucky enough to find several posts on mustang forums that all agreed with each other on what needed to be changed. It fit my year model and everything so I felt good about it. Otherwise, people suggested to try different things, but I wasn't comfortable plugging in random stuff.

The exhaust really is the best sound this car makes!! I'm still not completely satisfied with the audio, it's way better than what I started with, but still not where I want it. I'm going to keep working at it.

Glad to hear it helped. I know some vehicles have different codes. Thanks for watching!

I was the same way. I wasn't expecting award winning sound out of the speaker upgrade, but I was expecting more than what I got. The change with Forscan really changed things for me. Hope notice a good difference too!

Any update?

@@eronic404 not yet from me, I fell ill. I will try this week for sure.

@@eronic404 finally got to it, the answer is Yes it does make a difference for sure. Note that it will reset you radio's settings. I had to change my settings from 0200 to 0000, I own a 2015 Mustang.

@@nicklldoit okay great, I just ordered my forscan device today and it's coming tomorrow. Sadly though, my car has been sent to the body shop and I don't know how long it'll be before I get it back. But I'm definitely doing it once I get my hands back on my stang.

Good luck with it, hope it solves the issue for you too!

I sure will, take care!

I imagine you can still do it, although I'm not certain if it would be the exact same code change, since you have a different year model and equipment.

Thanks for the update. I believe different years with different options will require other codes, but I can't swear to it. Sorry it didn't work out for you.

Thanks for the info and thanks for watching! Seems to work in some cars but not all.

You could, especially if you are on the stock factory speakers as those are rather cheap. I upgraded mine to infinity which can handle much more power and you could also use the capacitor they include to limit it, but I never did have any issues. Take care.

I'm sorry I don't know the answer and can't help. They are changing the codes all the time for different vehicles, year models and options, so I'm not certain what might work in your case. Sorry couldn't help more.

I don't believe I noticed any change in the normal door chime. I did however notice that the backup warning beeping was now much quieter, which I liked.

@@RaymondLamb thank you. Mine is so loud I have to reset to original.

I had to do the same, I can't find any more information on why that happens to some cars. I've got a 22 gt with the 9 speakers

@@OfMiceAndMeh chime was coming out of the speaker after the change. I found a way to stop that with Forscan.

Here is a link to what I purchased. Never had an issue with it. www.amazon.com/gp/product/B083FML519/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Same here, ever figure it out?

Was the sub stock, did it come with the car? If so, it might be a different code, otherwise I'd think the same code my apply. Might depend on the year of the car too though, what year is your car? Good luck with it if you try it out.

Hope it works well for you, worked wonders for my setup!

Worked like a dream. We are rocking along now! Thanks again mate

That's awesome, so glad it worked for you too!

Hey Mike, the upper door speakers, tweeter and center channel are cheeeeeeeap! The lower door speakers are the best quality speaker that comes in the car, at least in my car. I don't know how much the stock speakers can handle, you can always try it and if they blow, it'll give you a good reason to replace, lol. If you change the setting I talked about in the video, you still get your low, mid, & high slider EQ settings on the head unit like normal. It just doesn't restrict the full range to the speakers any more and sounds way better. Let me know how the rear seat speaker replacement goes, that's next on my list too. I've just done everything in the front so far. You're right, lows are terrible, but changing this setting did manage to help, now my mirrors actually vibrate some, verses my ears bleeding from all the highs! You can check out my other video and see the difference in quality of those door speakers here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-9LeXuZJb9ho.html Consider subscribing if you feel like it, take it easy.

I imagine it would, but I think the code you might need could be different. I've read articles where different year models with other options require a different code than what I used. Good luck with it if you try it. Thanks for watching!

I don't 100% know for sure. I had the same issue when I upgraded to the infinity in the lower door, they sounded terrible. I swapped the stock speakers back in and left it alone. I never did try them again after changing the settings in Forscan, it might could help. Good luck with it!

@@RaymondLamb ok thanks for the answer. I will test it.

I'm not 100% sure if FORScan can deal with this entirely by itself. It probably can, but I'm not certain. I do remember reading somewhere on a forum that sometimes for things like this you have to take it to the dealer and they can activate it and that's all there is to it, but maybe that's the same thing you've already tried. Sorry I can't be of more help.

Thanks for the info!

Excellent question, and I don't know for sure. I think that is possibly handled by the amp and what it's set to send to the speaker, but you might can find another setting somewhere that could change that if it's not built in to the amp itself. I'm sorry I don't know the answer to that one.

I'm almost certain you can turn that off with Forscan as well. I never got around to adding a sub to mine to check further into it. Sorry I can't help you with the exact code or numbers to change.

Yes, those 350's have a great sound! I imagine the speaker settings would help you too. You would probably need to get on a forum to see if you could verify what the code was for your year and model, I think that's the only part that really changes. Good luck with it.

Blessings, thanks Ray.

Sorry, one more question. I know there are many forums and I am a part of one Mustang one already. Is there one in particular that you consider your go to place.

I typically find a lot of good info here: www.mustang6g.com/forums/ Just have to search or post if you don't find what you're looking for, but I've usually found what I needed.

@@RaymondLamb That is the forum I joined a while back. Thanks!

If you have a sub, you are in far better shape than I'm in and it might not be necessary. My biggest issue was after the speaker upgrade, I had almost no mids or lows and was not happy at all, so this helped bring some of that back. I still plan on adding a sub, but this helped until I get to that point.

@@RaymondLamb I’d recommend the cerwIn Vega spare tire sub. It’s pretty affordable with a built in amp just need to run wiring for $300. It also obviously goes where the spare tire is and does not take any trunk space. It also can still be put in with the spare still in

That’s a cool option, I’ll have to check that out. I’ve been looking at the JL Audio stealth box, but those things are super pricey, plus an amp and wiring kit.

I have the JL audio spare tire sub and Kenwood amp powering it. Hits pretty good!

Hey, that may work too, but I'm not sure, don't have experience with that part. I do know that there is another setting in FORScan that can disable the bass rolloff, but supposedly you don't want to do that if you don't have an aftermarket amp, which in my case I don't. That way it'll send the full signal straight to your custom amp and bypass the factory. In my case it just sent the full range through the factory amp and made everything sound sooooo much better. Hopefully get an amp and subwoofer down the road.

Going to try the lc2 pro with 2 12inch cerwin vegas I will let you how it came out. Thanks for the quick response

@@GARJENVETTE1 howd it go im in same boat

​@RaymondLamb do you know the setting to disable the bass roll off. I do have a aftermarket amp

I think the same theory would apply, but I imagine the exact code or number you'd need to change would be different. With the newer year model and different vehicle you might want to see if you can get on a forum somewhere and verify. Good luck with it!!

I imagine it would be very similar and that's basically all we are doing here as well. If you can make a backup in order to restore if something went crazy, I'd suggest that. But otherwise it's just a matter of finding the right number to flip. Good luck with it, hope you get it worked out!

@@RaymondLamb I actually tried it, it did seem louder but once you go too loud it sounds like shit. Lol.

Oh no lol. Have you upgraded the speakers yet? I believe the setting is there to protect the cheap freaking factory speakers. They probably distort like crazy.

Sorry, I don't know the answer to this one. I don't know if you could use a line output converter to do it, but I don't know if there is anything in forscan to bypass it entirely. Good luck with it!

Hey, I'm not certain if this fix will correct a distortion problem. My issues we with bass being cut out and it being almost nothing but highs, but it was crystal clear the entire time. I suppose if you found the right code to switch for your year model if couldn't hurt to try, as this would be an easy fix before you started looking for loose connections, etc. Good luck with it, hope you find the issue.

From what I understand a regular loc will work, but I'd still be concerned about the bass rolloff. Supposedly the lc2i solves this and outputs a clear bass signal, but I haven't tried it myself. Good luck with it!

@@RaymondLamb Thanks for your input! I agree, I am a little concerned about the roll off. Think I’m going to try the FORScan route (definitely the cheaper option). Appreciate the help and the super quick response!

www.amazon.com/dp/B083FML519?ref=ppx_pop_mob_ap_share Here is the one I used. Hope that helps.

As far as I know, you can do this trick on all Ford vehicles that have these options. BUT, I believe the codes are different from vehicle to vehicle and even year models, so you'd have to try to track down the specific code for your application. Sorry I don't have all that info. Thanks for watching!

@@RaymondLamb Where can I find these codes?

I had to search forums online to find the ones I needed for my year, make, model. I don't think there's a list or anything like that unfortunately. Wish I could help more.

I wish I had a clear answer for you. I haven't dealt with adding a subwoofer to the car yet, so I don't know if that might have something to do with it. I do know that just adding the infinity speakers did improve the sound overall, even before I made the adjustments with FORScan. So I don't think that should be an issue. If you use the balance/fade setting on the headunit, can you slide it left and right and hear anything out of those speakers? Good luck with the troubleshooting, hope you get it worked out!

I'm not entirely sure with that part. You can definitely try it to see if it makes it better and if you notice anything worse, change the setting back. I would think it might help getting a better original signal to your upgraded parts, but since mine is all stock except the speakers, I can't swear to it.

I can't say for certain, but dealers always look for any reason to deny something. I thought there was something about they had to prove that a mod or change caused the failure, but I'd hate to be in the position to prove it or fight with them to prove it. Nice thing about the FORScan is you can save a backup before you start and restore it if needed.

Never mind. I found out for myself. I do have to return to stock before FORSCAN can connect.

Sorry, I didn't see this, it was flagged for some reason. Sounds like you got it worked out already. You can send the people at FORScan a file and they can pick out the number you need and send it back to you. I was able to do this with mine as it was tuned also. You can also remove the tune, connect with FORScan and then add the tune back. FORScan will save the connection info and you can pick it from the list the next time, and not have to remove the tune each time. I've done it several times now with no issues. Hope you got the results you were after.

@@RaymondLamb yep. Got it done. Only side effect was it lowered the seatbelt alert tone. Which I actually like. 😂 lol

I imagine it would be. They all share the same software and hardware for the most part. You would probably have to find the specific code/number to change on yours though, as that probably is different. I'd look through some F-150 forums for the info, I bet you could find it. Good luck.

Sorry, I'm not certain you can turn them off completely with Forscan. I've only seen where you can make certain changes, but not disable completely. Not saying you can't do it, just that I haven't seen that as an option. Have you tried just unhooking the wires from inside the truck underneath the speaker? Still get the same problem? Good luck with it, hope you sort it out.

Sorry, I don't know if there is one just for that, or if it's all rolled into one setting. I wish I could help, I found most of my code info from digging through Mustang Forums, you might find something there. Good Luck with it!

I don't see any reason why it wouldn't work on a 2015, but the number you need to change is probably different. You might need to do some research to find the exact one you need to swap. The center channel I'm not sure if you can do, me personally I haven't seen anything about that one. Good luck with it!

Thanks for the tip. Thanks for watching!

That sucks, maybe there is a different code for the "upgraded" system.

@@RaymondLamb B&O is a better quality speaker so it doesn’t limit the eq at all. It’s soo bad though, thankfully I bought my car used and it just had that option. I didn’t pay that extra building the car to get the shit speakers haha.

Not sure just any dealer would do it, maybe if you had a friend that worked there or knew someone. I’m sure some would claim it might void part of a warranty since it’s changing what came stock from the factory, but you could always ask, couldn’t hurt.

@@RaymondLamb yeah I figured it will be more trouble than it's worth so I just ordered the adapter. Familiar with most brands diagnostic tools but do know most can't do much with fords so curious to see what a laptop and the software can do.

BTW after you did the mod did you try the lower door speakers you bought ? Might be better now?

That’s a good question and no I didn’t even think about it. When I first tried them I didn’t get hardly any mids or bass out of them at all so changed it back. I’m wondering now if this might’ve helped at all.

I bet it could. Sounds like the exact thing that I am adjusting with FORScan. You would just have to figure out the correct numbers to change it to.

@@RaymondLamb I think I just have to change it from EQ default with protection to the Crew Cab setting in the DSP menu of Forscan 783-02-01 x*xx (what number does this say for you?) Vehicle EQ Selection: 0=Unconfigured (default EQ with protection filtering), 1=P552 Super Cab, 2=P552 Crew Cab, 3=CD539N-Edge, 4-7=reserved

I don't have the tool yet..just assuming this is my issue but need someone to confirm what setting they have

2016. For me lol
