770 Meridian Sound System - Speaker Question
Ok...I am happy to report, that my 2 year saga of the stereo issue has been fully resolved today, as a result of the recent TSB! Yup, I can hardly believe it...
This was my cars 4th trip in to attempt to get it resolved and this did it (dynomat, tape, replaced speakers, replaced amp along the way) & as many suspected, it was likely software all along (which is what the tsb modifies).
It has completely resolved the annoying 'tweeter buzz' noise. I would say that beyond the elimination of the buzzing (wrong frequencies going to the tweeter), the overall stereo sounds better as well.
I would say that the stereo is 'good', not a 'great' stereo, but I'm sure this is the quality that was intended out of the system. I am completely fine with it. This car is awesome and the stereo was just a nagging annoyance that just was just really unfortunate.
Still very disappointed on how JNA handled the issue, on the whole! It was constant avoidance/denial, when there was obviously something wrong with many vehicles. They have a long way to go to be competitive with the more proven manufacturers in this area (customer satisfaction/service)....but, it's water under the bridge at this point for me. I'm just happy I've got the killer crackle of the exhaust, PLUS a decent sounding stereo for when i need/want that.
Now...in an ironic twist of fate. After picking up the car from the dealership this afternoon and giving it a nice drive to test the stereo (and enjoy a sunny day finally), I was on the freeway, when a piece of drywall flew out of a construction truck ahead of me (over one lane) and smacked the R right in the nose! I couldn't believe it. It happened so fast...i didn't even want to pull over and look, as i knew I took a direct hit (nothing i could do to avoid)! when I did...yup, front bumper and grill damage! Sh*t
I had a full clear bra on the car and that did seem to reduce a fair amount of the damage, but not completely unfortunately. drywall went right thru in a few spots and caused scratches/gouges and also broke the lower part of the honeycomb grill). Unbelievable!
Oh well, no one was hurt fortunately, but i will be out my deductible on a claim and without the car for 6+ days (estimated). Such a buzz-kill on an otherwise great day.
Anyway...for the many of you that have been having the stereo issue, get your car scheduled for the TSB and enjoy how the stereo had meant to sound! ...and, be careful on that test drive! ;-)

i didn't. it happened so fast & the truck was a few cars up in the adjacent lane. i didn't have anywhere to go (left was wall, right were cars). i slowed down as a result and didn't fully get my wits back together in time to process speeding up to catch up with the truck.
i pulled off the freeway an exit or two up to check the damage and make sure nothing was lodged under the car, etc.
in hindsight, i guess i would have tracked the truck down, but it just didn't come to me at the time.

Take it to another dealer. Its a bulletin. Regardless if you have the symptoms, if the software isn't the correct version they need to update it.
Not hard at all. I just told him that I was hearing a buzzing sound coming from the tweeter speakers, and that I had found the technical bulletin.
I just got this update done yesterday, i just told my SA to make a service appointment for audio quality issues, and when i brought the car in, described the issue exactly as its written on the TSB, and suggested he write the TSB# down on the work order. EZPZ, they did the update and i had the car back the next day(also had a squeeking driver window that turned out to be a rock stuck in the trim)
I also got a run around from my dealer when I tried to schedule the update and was told that they cannot and do not just implement bulletins. He said they need to know that the problem exists on my car before they will do anything.
So, I described the problem exactly as described in the bulletin, they scheduled the work, and the result is fantastic.
I discussed this policy with Jaguar customer service and they simply said it is completely up to the dealer.

Called my service guy this morning and was prepared to do battle but he said he had added it to the techs to-do list while they have my car for some other recall stuff (the canister/pipe one)...now if there was a way to confirm it gets done without the SDD tool...
If you're displeased with the stereo right now then you should notice an obvious improvement.
My car is currently hibernating, but I have been complaining about the stereo from the day I picked up the car. They originally jumped on the problem and replaced the amp to no avail. My service guy said last week he was not aware of the TSB. As soon as the weather clears I'm bringing it in, and TSB in hand. Thanks to all here.
I'm reviving this channel as I have recently been doing some work on my Meridian sound system. Background: I worked in the custom/competitive car audio world for 20 plus years so I have pretty extensive experience with OEM and aftermarket audio systems. I too was severely underwhelmed by the sound quality of the OEM Meridian system in my F-Type. Looking at the hardware that this car is equipped with, it was confusing as to why it sounded so bad. (poor sound stage, poorly defined bass and weird flopping sounds coming from the rear woofers at low to mid volume) Fortunately I didn't have the tweeter crackle issue that may have pointed out so I may be lucky or the firmware was updated to correct this. (likely an incorrect crossover setting). I decided to do the most effective upgrade (in my opinion) which was to install a DSP embedded amplifier (Audison AF C8.14 Bit) so that I could create my own tuning profiles vs how Jaguar/Meridian approached this system tuning.
The first thing I tested was to disconnect the rear woofers (the source of the Flopping sound) just to see if it made a difference. All I can say is "WOW" what a difference! I now had significantly improved mid bass definition and low frequency output at all volume levels. The sound stage moved to the front of the cabin as well. This tells me that Jaguar had the rear woofers tuned out of phase with the front door woofers. This bad tuning also caused the sound stage to be disconnected. To be honest, I was tempted to forego the amp install as I was pleased with the sound quality improvement from just removing the 2 rear woofers from the equation but I felt there was more to be gained with my own tuning. I installed the Audison amp behind the center console removable panel using the existing bracket that covers the telematics module. (I 3D printed an adapter to attach to the OEM bracket) This was very convenient as all of the OEM amplifier wiring passes right next to the new location. I utilized the 6 front channels to acquire a full range signal source for the 8 Audison amp channels to run the front stage. (tweeters, mids, woofers and center channel) I used the 8th channel on the Audison to power a 10" sub enclosure that I am using temporarily until I fabricate a fiberglass, sealed custom enclosure. I bought a small 4 channel amp incase I wanted to power the rear mid range drivers but I elected to leave them connected to the OEM amp for simplicity sake. All I can say is that the OEM speakers are in fact adequate when powered and tuned with an aftermarket amplifier. My car sounds quite impressive now and all I technically did was correct for the amateurish tuning that Meridian imposed on Jaguars F-Type customers. If there was a way that we could access the OEM DSP and install an aftermarket tune, there would no longer be an issue with the OEM system because the hardware isn't really the problem. I will try to update this post with some pics as soon as I get the chance. Everyone can feel that all is not lost when it comes to getting a great sounding system in their F-Type without sourcing hard to find replacement speakers or breaking the bank.
Cheers!
