that'is strange it does not seems that the Hu has separate power for tweeter and woofer . The tweeter and woofer come from the same amplifier . Theu are 2 stereo amplifiers >>>for front & the rear , in total we have 8 sepakers (4 tweeters and 4 woofer for Front /rear)

I'm only amplifying the front, don't really care about the rear. that chart only has the speakers I'm connecting I removed the others to make the diagram simplified.
ok i understand
can you make a build thread with your car ? (i am going to do the same )
Let me know about the Fix JLaudio , it seems to be very good and it has an ouput digital
Installed the JL Audio Fix82 and calibrated the summed factory amp output channels (Dash Mid/Tweet - Front Door Woofers)
I'm combining factory amp output (high level) using only channel 1-4. You can see a graphical representation of ingress (Red/Violet Line) and combined fixed egress (Orange Line)
That's good ...
But in my opinion if you look after the 2 curves ,you will realise that the "stock tweeters" are not tweeters , these are 'mid-tweet' , the crossover point is located beetween 1.2k and 2.5k .That seems a litle low for this kind of tweeter, that is why i fitted a coaxial first and after that i am going to 3 way with the ODR set up ...
The better set-up to get a correct sound stage ,is to begin at 300hz <> 800hz to the mid (= high pass for the dash ).
Even if the focal kit surpasses the oem speajers, the original kit will always have a better "staging" due to the crossovers frequency.
There is a 2/3 way interesting speakers set that exists :

Thanks for the detailed information, once I get it all up and working I'll run in through its paces, if I'm dissatisfied with the staging I'll rip it out and start over. I've done this exact speaker configuration before and never had an issue.
You will not be disapointed, this Focal kit sounds very good , iam talking about"staging" and this is in second in listening for a lot of people
As a SQL judge and competitor for MECA, USACI, IASCA I much prefer a well placed and natural sound stage over having a flat frequency response with an RTA. It was always easier to tune a stereo with a flat response with pink noise, than have a well placed sound stage that accurately replicated instruments and vocals. I had two Eq/time delay settings for these competitions.
But, BRAVO to the OP for what he's doing!
As a side note, do you guys feel the dash is deep enough and the windshield is sloped well enough with respect to the driver's seat to recreate a sound stage that it sounds like it's coming from outside the car on the hood? I've been itchy to determine if it's worth the investment. Lol my wife would say no, but the audiophile in me wants to rip it all out and do something like the OP and some......

All the pictures and examples I'm posting are within hours of getting everything installed, I flat frequency curve is not what I'm after nor should anyone strive for a flat response.

I have a 3 inch mid in the factory tweeter location and find there are major dips so building pillars will be my next project. So I don't recommend putting a mid or tweeter in there.
