Drew,
I have the HK upgrade system. This came with 8" subwoofer and the panel is specific to this application. So, behind my panel there is room to add in a sub and flush mount it. If you do not get eh HK upgrade, then your panel will be different. The drivers side panel has a cubby in the panel and if the passenger side is like this then it is not an easy work around. If your panel is flat, then you can do a cutout but it wont look perfect or be flush. You guys need to remember that the cars with different sound systems have different specs and no one is sharing that info or posting your pics so it is difficult to answer these questions.
The bottom line is that to get the look you are looking for, you need to buy the HK panel, but I am sure it is expensive and may not be available at all.
All those speaker brands you mentioned are fine. Size and type is the most important. Even still, these will require some modifications as the stock speaker have baskets that extend forward towards the door panels. So, you need to build templates to move the new speaker into the correct position.
