Door pods

[clarky]

OK, i'm after links or advice on actually mounting door pods. I have seen how to make them, but they always neglect how to actually mount them. I have a 98 cupra, and as you may know behind the speaker grills are 2 screws which actually screw the door card to the door. Now if i built a door pod, how would i make it so that it would look good but still allow me to get to these screws. This has baffled me and a friend for over a year now, and has resulted in my expensive components just sitting on MDF rings in the existing location without grill. I would really like some angled mounts and also to raise the tweeters upto the plastic trim where the wing mirrors are for focus reasons. How would i mount a small tweeter build here too??
Oh yeah, and how do i stop the doors vibrating from bass? I have them sound proofed with dynamat/brown bread on both the inner and outta skin, and i have draft excluder strip (the stuff you put round your front door made of foam) around the edge of the door card but it still vibrates like it's not tight. would new snap clips things help???

Any advice would be great thanks.
