Mobridge DA-G2.Pro A2B Ford Preamp & DSP Help

[SnareDrum]

Anyone running this with their setup who could possibly offer me some insight? I had the factory 8-speaker B&O and removed it. I replaced the factory amplifier with the Mobridge DA-G2.Pro A2B Preamp & DSP, Kicker amplifier and Kicker speakers (KS components in the front and KS coaxial in the rear). It works well and sounds good, but I'm unable to get the chimes to play through the speakers.

Obviously there's 2 DTCs in Forscan with the APIM and the ACM - Lost connection with Module D (I'm guessing this is the factory amp). Not sure if there's code I need to change to address this. I've cleared the DTCs but they return.

I reset the APIM, ACM, and IPC yet all the chimes continue to play through the cluster. In the DSP I have the chimes set to play through the front speakers so I don't think its a DSP related config issue.

One other thing and I'm not sure if this is an issue with my time alignment or maybe a defect with one of my component speakers, but the tweeter on the passenger side has this really nasty "EEEE" sound around 8khz. I had to cut out at least 12-14db and it's still slightly audible. I did time alignment with my laser measuring device in the driver seat aiming the laser at the center of each woofer from about where my head would be.

I'm curious about the whole setup. Was looking at this unit but couldn't find any info on integration or quality. Following.

It was very easy to setup and has a very simple configuration program. Only thing I wish you could do was connect to it wirelessly because it uses USB to connect to a laptop. I know a lot of people went with the Nav-TV, but I'm not seeing a lot of people using this for our truck just yet. This unit was one of the A2B devices that @SoundsGoodStereo mentioned in a DM to me. SGS do you guys have any advice on what I'm dealing with?

Just a quick update. I had neglected to mention that I reached out to Mobridge this morning and they responded pretty quickly. The did say that the unit is supposed to have the chimes run through the speakers like factory; however, they've had issues with some model years from recent software updates. Looks like they're going to send over some beta software for me to try. This was my first time contacting them for support and they were pretty quick.

It's been a while since we played with this unit. As far as the "EEEEE", did you run power + ground to the battery or are you using a different ground? Also, make sure your connections to the speakers are proper, not shorted out and no extra strands of wire are touching.

For the Chimes, do you have the jumper settings set on the unit? If you have clicked every everywhere, it's probably in need of a firmware update. We have the team from MoBrdige coming to our shop next month and going to work with us to do some creative features that drive us crazy, so maybe we can talk to them about chimes.

I have separate power and ground running to the battery. I ran the cables under the truck on the frame and drilled holes through the rear passenger floor like you guys do. I'll have to double check on those connections and get back to you. When I say "EEE" I'm referring to sounds associated with certain frequency bands...picked this up with ear training for my audio recording hobby. Sounds like it's around 8khz, maybe around 4khz as well. It's so odd I almost thought the tweeter or the passive crossover was bad.

Something with the X-Over is possible. Hop in the passenger side and see if you can identify the driver's side doing the same thing. At higher frequencies, the driver's side rolls off on some tweeters, so it might sound like only the passenger side is doing it. Then start swapping left/right on the X-overs, amplifier, etc to see if you can narrow it down.

I was looking at the amp and the DSP. Just a black hole when it comes to these guys on information. Did find some positive and negatives about them. Offered to put it through its paces if priced right, ultimately decided it wasn't worth the hassle. I was concerned about the chimes and didn't get a clear answer on it. When installing my pac A2B, I was connected to FDRS and it installed / configured new lin bus module. While the DSP as a truck module has vanished as the factory amp isn't in it any longer, all works as it should.

At this point their support is a black hole. Right after I got a response to them I replied twice and still haven't got a response. This was over a week ago at this point. Kind of disappointed because initially I was satisfied, but now I keep running into issues.

Wow. Hopefully they get it together. Have you inspected your wiring? There are several cab grounding points in the back of the cab. If you can create the noise on-demand, try running a jumper between the ground point on the back right wall of the cab and the amp. What motor do you have?

I have a PB and the electrical system is a little different in its layout vs the ICE only models as the main battery connects to the BCMC's main 12v busbar via an isolator (a bunch of mosfets on a heatsink in a NC position) with 6ga on one side and 8ga on the other. Its primary purpose is to keep the under hood batt charged. The DCDC is powered by the HV system (essentially a water cooled 280v DC to 14v DC voltage converter capable of continual 220a output) with a separate aux battery on the BCMC's 12v bus. I replaced the aux battery with an LFP that can handle transient loads at the 14.2v the DCDC can be made to run at (connects to the BCMCs 12v bus via a discrete 4ga wire). I connected very short 8ga runs to the frame and the cab (where the LFP ties into the cab ground) where they they then both combine into a junction block that feeds the amp. Their combined resistance is better than a dedicated 1/0 run to the batt.

With the amp peaking at 115 amps of current draw the electrical system doesn't blink. I was seeing less than .1v drop on the system with a scope. I'm going to do more tests once this storm passes. Hope you get a resolution -- not a fun spot to be in.

I have the 5.0 and I ran a dedicated ground wire to the battery. This issue I have seems to be intermittent. I think it may have been a time alignment issue and also a dsp issue. It’s beyond my knowledge at this point. Need to do more research.

Apologies about this, it seems like your emails went to spam I have responded now. I have been flat out the last couple of weeks and haven't been checking the support tickets as religiously as I normally do.
Anyway, I just finished a couple of days at Sounds Good Stereo working on their F150s and we now have all the information we need to fix chimes on the DA-G2 and the Zen.

Are you able to get a recording of the noise to send to me?

Chimes are supposed to be supported same as factory and are fully mappable and gain adjustable. It seems like ford changed a couple of messages on CAN at some point and broke some functionality. Fix is coming very soon.

Given the PAC was developed after both the DA-G2 and the Zen I can see how it wouldnt have this problem.

Just finished installing the Mobridge K2 8.1.1 Channel DSP Amplifier in my 22 B&O Unleashed and all is working well with the exception of the chimes. Curious if this amp too will require a firmware update to address? I will say I've had the chimes bounce between the instrument cluster and speakers from time to time (assuming Ford related issue/matter) but since I've installed the Mobridge, I'm only hearing chimes from cluster. In addition, any head unit touchscreen beeps I used to have no longer come through. @mObridge any info or do you know if this will amp will be included for fix?

The chime fix is coming to all platforms in the next couple of weeks. I will post on here when its ready.
