Distorting door speaker.

[Turborave]

Hello! I have the B&O system in my 2019 Lariat. I listen to mostly BMP and Diplo's Revolution on XM, from what i remember, the sound was good for a while, but now i am noticing distortion, even at low volume on what seems like my front door speakers. One could refer to it as "farting" when there is bass. As i said, i dont remember it being like this initially, but has gotten this way over the last 5 months or so. anyone have bad sound from their B&O system? how hard are the door speakers to replace? i don't want to mess with the amp and stuff.. but i would consider a door speaker swap.

I'm having the same issue and it's only coming from the driver's side front door. I'm waiting for warmer weather to pull the door panel off and see if the speaker is damaged. It only happens on certain songs which I'm guessing is when it plays a certain frequency. Not all bass does it either and it doesn't have to be anything thumping, just at normal listening level less than 10 on the volume control.

Same! but its my passenger door... in my head it think its because when i had my truck in at the shop, they cranked the tunes and messed up my speaker. but thats probably not true!

Please let us know if you discover a fix or anything. My driver door is doing the same thing. I just noticed recently. Not always though, seems to be certain tracks and not others.

So i sat in my garage for a bit after a short drive... the song by SZA, Good Days (remix) was on Diplo's Revolution which makes my speaker buzz, i noticed if i pushed on the passenger side door handle bar thing and i noticed the buzzing went away. so, i wonder if its just something loosish in the door and not actually the speaker.

this is the song if you want to test (phone to bluetooth):

I had this same problem on my 2019 Lariat w/ B&O audio. My driver's side door had a buzz which sounded like it was originating somewhere behind the top 1/3rd of the door card. The noise was associated with a very narrow bass frequency range, and would go away if I pulled on the door grab handle. Initially, my truck sounded great, and the buzz showed up a few months into ownership, after I had already taken the door apart once to install sound deadening.

The problem was not the speaker at all. There are mechanical control cables for the door locks and latches and the window lift and lower system that are routed between the outer door skin and the inner door skin. On my truck, on the driver's side, these control cables were run very, very close to the inner door skin -- they would *just* kiss the inner skin when the bass was shaking the inner skin and the control cables, which would cause the buzzing noise.

I found and solved the problem as follows. The work is blind as you can't see the areas where the cables contact the inner skin, but feel around and it should be fairly clear what needs to happen.

• Take off the interior door panel. Here is a good guide.
• With the heel or butt of your hand, gently and rhythmically strike the inner door skin. You should be able to hear roughly where the cables are buzzing against the inner door skin
• Reach into the space between the inner and outer door skins through the center/bottom cutout in the inner skin
• Guide your hand upward and feel around for control cables. On my truck, there was a point where two cables crossed each other; this was the region where the cable(s) were close to the inner door skin. I've indicated this region in the image below with a red box.
• Once you have found the region where the cables are closest to the door skin, apply some self-adhesive foam rubber cushioning strip to the door skin in this region, between the cables and the inner skin, and also wrap the two cables themselves. You just want to apply a soft treatment to the surfaces where the cables may buzz against the inner skin.
• I also applied foam rubber tape to the control cable that runs between the door card and the inner skin as it appears to run very close to the skin as well. I've indicated the cable in the image below with a green arrow.
• Reassemble the door and door interior panel, but before you button it all up, let the bass bump! You should be able to tell immediately whether or not the problem has been fixed or if you'll have to go back in and add more cushioning.

This was a super irritating issue and took me a while to find and fix, I had the door apart about 5 times before solving the problem. Hopefully this information is able to help someone out there!

Well, before you go tearing your door apart, put your ear right by the speaker. If you hear the distortion loud and clear from there, it's no question you have a speaker issue. You'll be able to tell from localized listening if it's coming from the speaker or elsewhere in the door.

If it's the speaker, it could be a warped voice coil, a partially disconnected or or broke solder connection on a tinsel lead, adhesive on the voice coil former disconnecting from the cone, or any of the suspension components coming apart. In any case the solution is the same - you need the speaker replaced. It can probably be replaced under warranty.

Hi, I had noticed intermittent distorted sound from the front door speakers of my 2019 Ranger XLT. This presented on hotter days. When first noticed, I thought it was bad radio reception as it appeared only to be when announcers spoke. over time it became worse and effected the sound of a phone call. I also noticed that the engine noise was also louder. I took the vehicle to a Ford dealer who said it would be $200 an hour to diagnose the possible problems. I decided to replace the front door speakers with Powerbase OE652-FD 6.5" speakers as the only common areas were the speakers and the radio unit. The day I installed the speakers was quite warm and the problem was evident. before replacing the speakers I manually exercised the cones and noticed a scratchy feel and sound.
On replacing the speakers the problem is no longer. Once the original speakers cool the scratchy feel and sound had gone. (Cheap Speakers)
I hope this helps as this may also be a problem when cold.
