Please keep me updated on that place in Virginia, there is a independent Jaguar place in Baltimore I talked about doing this, they let me know over the phone they were willing to try it is a 4 hour drive...where are you getting the part number?

 

The part number I started with in this thread is the generic number on the box, but it's also listed as AUD4-16 and PREM16, which is on all the prior Surround amps in this thread. The PN on the box doesn't otherwise match a Jaguar/Land Rover number, which is normal.

However, I have access to PartsLink24, which is a professional-level parts database for repair facilities, and the Jaguar part number that comes back for my car and the one in a known 2023 with Meridian Surround have the same number via PartsLink24.

On PartsLink24, the info for the part also states that it is used from VINs ending in NCK79228 through to the end of the production run in models equipped with BOTH Hi Line Audio System - 600 W and Premium Audio 1280 W. Note that on all the listings, they break down as 400/600/1280/2500 watt amplifiers depending on level (we never got an audio system in the F-Type with the 2500 watt amplifier). The 600 amp got used for the 380 system, and the 1280 amp for the 770 system. So, given that it has the correct PREM16 and also a part number matching the car with the known 770 system in a 2023, I'm strongly leaning that it will work, which matches with what the British tuners are saying as well, based upon VIN.

 

There's a company here in the UK that perform the upgrade, so must be possible and I'm sure someone in the US must offer the service.
