2010 Range Rover HSE Speaker Issues and Tweeter Replacement

About a week ago I experienced crackle noises and hissing from the front passenger, right side speakers (Tweeter and mid-range). Oddly, I hadn't been blasting music, but this occurred right after I turned the car on. I was hoping that it might be a wiring issue, but sure enough, it seems that the speakers are blown. My Range is a 2010 HSE black on black, with about 92,000 miles.

I took the vehicle to my local land rover dealer, and 200 bucks later they "diagnosed" the issue and said I needed a new amplifier ($2200) and new passenger door panel ($1800) because the midrange speaker is not removable. Land Rover said my amplifier was pushing 14 volts to the damaged speaker on the passenger side and 9 volts to the undamaged speaker on the driver side.

I then took my rover to a car audio shop, and they said that the amplifier is fine (they explained that the damaged speaker was accumulating the extra power and thus the higher voltage and usually an amplifer failure means all speakers stop working), and that the speaker mid range was blown. So they disconnected it for now, but they confirmed that I would need a whole door panel to get that mid-range speaker back.

With that in mind, I'd love some tips:

1) My tweeter is hissing. What's the best method to disconnect the passenger tweeter to at least stop the hissing while I wait for new parts to come in? Also, any instructions for replacing the tweeter would be great. I can't seem to find this procedure in the service manual.

2) Are there any workarounds to replacing the mid-range speaker without replacing the whole door panel? I realize that from the looks of things, it looks darn near impossible? Otherwise I think my best bet is to buy a used door panel for about $450 on ebay.

3) Any chance my amplifier is indeed malfunctioning? I did witness the car audio shop plug in an external speaker to the same hookup as my damaged mid-range speaker and it was playing fine. I just want to avoid installing a new door panel speaker and having it blow out again.

Many thanks in advance! Other than this speaker issue, my Range puts a smile on my face whenever I jump in : )

Not likely. Ford purchased Land Rover from BMW clear back in 2000. In 1999 BMW changed Land Rover products over to Bosch electronics and systems. Due to already contracted supply chains Ford moved forward with production of the first gen L322 designed by and engines supplied by BMW. Ford immediately started developing the second gen L322 with Jag engined drive train. Ford ditched most of the BMW technology for the new design going with off the shelf items from Ford to save production costs. The result was the 2006 L322, BMW components and all new Ford/Jag drive train. 2007 was the first year for all Ford production and new/renewed supply chains. 2010 was the first year for the third gen L322 with 5.0L engines. Any BMW parts would most likely have been ditched back after the 2006 production run.
Just an FYI on BMW parts for a later than 06 RR……I have an 07 supercharged and it in fact has TONS of BMW electronics embedded in it, next to FOMOCO and Bosch. It wasn’t till the next gen range rovers that things seriously changed. A lot of interior plastic finishes on the dash of an L322 are mostly BMW designed. The sad thing is about cars, is that most people buy into the bullshit that each manufacturer use parts exclusively for their brand and no one else does. It does seem that way at first glance. But if you do research, most cars use the same **** parts that others use (especially electronics). It’s all in the part numbers. You may pay more if it has a certain brand stamped on it. You just got to do some research and get creative. But most car manufacturers around the world use the same parts manufacturers. This was the number one reason why the government stepped in back in 2008 and started bailing out auto manufacturers. If one failed, it would’ve crippled them all, starting with the supply chain. Current example is now in 2021 with the silicon chips. Don’t be afraid to cut in to something that is already broke. The key is to find out who owned the company at the time or before it was built. Research similar cars from those companies, find the product from the less expensive car and compare the two. I’ve found Hyundai electronics that worked on my old disco2 that were lottery 30% of the cost of the LR ones or even the Borg Warner replacement from the auto parts store (example: fuel tank evap solenoid for the Bosch 4.0)
