I got a notification of a reply but that thread is now gone from the general discussion thread. I've posted the text here again with my response:
Here is the message that has just been posted:

I will be replacing all six speakers in the door, Add a four channel amp, And also a powered subwoofer.
I know in my car there are only two channels in each door, Low pass & High pass. The 3.5 and tweeter get the same signal.
I have some installation experience on at least a dozen other cars in the past, But any tips would be greatly appreciated.
Or let me know what model and brand of product you have inside your cars.
Any comment will also help too.

You mention there are 2 channels going to the door: where are they coming from (ie is there a crossover somewhere)? I see resistors or something on the factory 3.5 and tweeter so I can see that's how they are splitting that signal but where is the low pass being crossover'd from?
I'm just about to put new wires and external crossovers, but knowing this info would be helpful.
In the meantime, I've installed the following:
Hertz speakers:
Hertz Space 8L midbass
Hertz Space 1 tweeters
Hertz HL70 3.5" midranges
The Space 1 tweeters need to use the shallow chamber included to fit the factory door sail spots.
These are all wired to the factory wiring, which is then connected via a wiring harness to a Kenwood DNX7120 headunit.
Overall the sound is good but the tweeters sound bright and the bass a little weaker than I' hoped, but I think this may be due to the fact no crossovers are splitting the frequencies. I have the Hertz custom crossovers (3W.10) 3 way crossovers ordered and plan to run new speaker wiring now. I was hoping to avoid this, but I guess the upside is I can then add an amp in the future.
I can post pics of my Kenwood DNX installation and the speaker installs, but I'm not sure if there's much interest given no replies so far (except yours),
