I used the center of the factory tweeter grilles for symmetry. The pods are are mounted with a thru bolt. Fender washers on both sides sturdies the trim piece. The pic showing the external nut was just reference. A nylon nut was installed inside the pod before mounting the speaker. The rear thing is a cannon plug backshell used in aviation electrical connections. I may go to the usual lamp hardware tho and rewrap. The windshield reflections are minimal practically null in this location. The driver plane is about 2" rear of the upmost part of the windshield. Ive found I need to move the driver side a touch more on axis. It messes with cosmetics so Im gonna do the same pods in the same way but up to 4" diameter pods. They will look more spherical and gimme a touch more volume to more represent the graphing of the ES-3. Ive jammed the mid and tweet combo for a bit already in a crude sense but its sounding fantastic already. Fixin to get on the doors here shortly. I just ordered the bill of materials to get going on that. This is the first time Ive been anal about deadening. Other builds usually stopped at CLD. Second Skin plug......Im not using anything else ever...lol and I ve used a few to know why. The deadening still continues as I will be doing liquid under the whole car in the coming months. It is very coffin like and very rewarding. I can only hear the external components of the car besides some minor buzzes that I will tackle here as I go. The wire installation is to Boeing Standard Wiring Practices and I have all the manual references and photos of how it would apply on aircraft. Mostly the engines as thats what I build and I routinely help avionics harness our engines so I thought itd be cool to theme the build accordingly. Im still in the rules for IASCA too so win win. Plus Moe Sabourin said if its FFA legit than its good enough for a car. As elaborate as it looks the same practice can be followed with the usual bay install hardware, its all about approach I suppose. I didnt and will not use zip ties in this build only because we avoid them at work. I would use them otherwise tho. Thanks for your feedback, I'll answer all that I can. Ive done a lot of tinkering and this build is just to show what I can do from a personal standpoint. I think I would put the same ethic into any build or would be customers build.......actually I WOULD its just how I am lol
