456 Speaker Upgrade Project from Scuderia Audio

I finally have a bit of free time to concentrate on the gorgeous 456 model.

Using Auto CAD, I designed some stainless brackets that will be utilized to replace the 5 x 7 speakers in the doors with Focal "Flax Series" 5 1/4" drivers. Hyper directional tweeter pods were also designed (similar to the 360/430/458/488/F8/599 etc.) to replace the stock black plastic triangles. These will hold the Focal tweeters at a precise angle to fire the sound straight at the occupants for perfect stereo imaging.
More stainless brackets have been designed (and will be here in about a week) to replace the tiny drivers at the base of the rear seats with the same monster mini subwoofers used in the 360/430 hi-fi system upgrades.
And finally, the speakers in the rear side panels will be replaced with matching 3 inch Focal Flax drivers. I'm taking four speakers to the machine shop tomorrow morning to have a single extra mounting hole precision drilled into the aluminum speaker basket to facilitate a bolt-in replacement scheme. I'll also be paying them to fabricate a fixture that will allow me to drill the third hole in the speaker basket without the need for an NC mill.

The rear subwoofer adapter plates arrived today. I haven't painted them black yet but here is a test fit.
Believe me when I tell you that these are the largest subwoofers you can fit in that area.

The hyper directional 456 specific tweeter pods have arrived.
These replace the stock black plastic triangles that sit at the bottom of the A pillar in the doors. The angle of these tweeters fire the sound right straight at the occupants for perfect stereo imaging.

I picked up the fixture this morning. It works well. However, I have to enlarge the speaker mounting holes a bit because the studs protruding from the panel are not exactly orthogonal to the panel. In the end, the speaker is a good fit.

Okay, the system is complete and ready to ship: https://www.ferrarichat.com/forum/threads/scuderia-audio-presents-ferrari-456-super-system.690855/

 

The 456 (not M) has an amplifier next to the CD changer in the trunk (part #155713) and both the amp and the CD changer are held in place by an assembly of brackets (part #157024).
Fleabay does not have either of these items so I'm a bit stuck. I need to look at the amp to see if I can find the electrical connectors that would allow me to design and manufacture a 100% plug and play harness to replace the stock amp with a high end amp with a built in digital signal processor. The amp bracket would help me to design an adapter plate so that the new amp would be a bolt in item.

Just checking on the off chance that anyone out there in 456 land has one or both of these parts they could lend me for a couple of days.
