It confirmed for me that my parallel wiring scheme for the two 8ohm dual voice coil DSP speakers is a 2ohm load.

My Power Acoustik RZ1-2300D mono block amp is happy with that and is rated at 1400 watts @ 2ohms.

^Yep very helpful! I guess I will have to follow some wires to see how the factory DVC 8ohm DSP subs are wired - However I think this calculator does not anticipate each coil is run by a separate channel of the amp (as we discovered previously, factory wiring uses a channel per voice coil)

If the factory DSP amp sends approx 40W RMS to each voice coil at 8ohms, wondering if I can just use a lower RMS power sub SVC (at 8ohms) and bridge both channels together for each- Just imagine this times 2 - I figure use 2 channels per sub on a SVC setup to replicate this. Or does this not make sense?

RB i believe you have to calculate the subs impedance as if there are four 8 ohm subs.

So you made me double check the possibility of using the original tweeter mounts with the JL C2-600 tweeters...After removing the factory tweeter from the mount the JL tweeter is still too large to fit in without modification to mount. So I did what Prop did but then had to slice open the side and then silicone the inside and press in the JL tweeter in.
Now I'm happier. I have to remove the door card anyhow so I may as well remove the other JL tweeters I just have sitting in the styrafoam and use the mounts Name:  IMG_20170324_145617.jpg

Awesome. My method was a bit different. I didn't split the mounts. I carved them to be larger with a rotary sander. Tomato, tomahto, I say.

Is that an E31 I see back there?

I love those things. I have a feeling that one of the reasons is bc I've never driven one. I do remember the hell that was the reception of them after the E24.

So today I installed the tweeters with factory mount and I also got rid of the door rattles by means of putting in a few foam insulation tape pieces around perimeter of hole in door of the mid-bass speaker (when speaker is fitted back in hole it rests on the foam and the foam compresses a LOT as speaker tightened down. I tested and all rattles gone now. I left a small gap between each insulation piece I stuck to the door metal so air could escape and not rattle things inside the door. Worked like a charm.
