Atcer2018 I appreciate your recommendations, actually everyone's feedback. I purchased the Infinity's because they're unique. The midrange and tweeter portion of the 3 way speaker actually point up toward you at an angle. They're different. Never seen ones like this. Follow my logic on this and in no way am I not considering your recommendations.
As you know I've made a major improvement modifying the aftermarket dash speakers by making them 8ohm and full range with the 100hz cutoff. Unless anyone tries this I'm just typing in the wind. The front soundstage changes dramatically. Front gets big. Guitar leads, vocals, horns not brash but sweet and smooth. "In your face" change because this puts more power in the midrange that's just not there out of the box. They sound like tweeters out of the box at 4ohms and 8K crossover. 8K, seriously? Look at the chart if you don't believe me. Bringing all of the sound out of the dash opens up the next step.
I did buy some different caps to tailor the crossover to a more protective 150hz, something I discussed with a Crutchfield tech. I'm changing the 270uf cap to 125uf. Anyone interested here's a nifty chart for crossover values and Impedance of the speakers, scroll down the page.
https://www.sonicelectronix.com/item-17962-The-Install-Bay-BB99.html If you look at the chart and see where the 8k crossover is that's how much sound is lost in the stock aftermarket configuration. I put all that back. One other thing I noticed for some reason the front door stock speakers got better. My pant legs move now from the bass. This is using the stock system. Maybe a bit more current is being pushed to the doors with this new dash speaker scheme.
The next step with this huge dash improvement my intent is to put some more mid to high sound up and in front of me from the doors. With the full sound dash combined with the up firing door speakers blowing into it, it's the only way I can add more sound in the front of me, not just bass, no other way. I believe the mids and high will connect together with the dash this way. Maybe with the just the tin of tweeters like you all have this wouldn't be such a good idea, very noticeable. I can always put foam over the parts that don't work.
Also, having played for 35years on stage in a band I'm a little less disturbed by less than perfect sound positioning. It's a truck, low on my list. I may not notice it because I'm more used to being enveloped than sitting facing the music. I do know a little about sound, I have a sound studio and 40 years working in electronics. No Dave Haddon, I'm older than you.
Thank you all. NETAudio has contacted me with the rest I need. I'm going to put the key200.4 in first with the stock speakers and my new dash speaker. Play around with it. I'll make my door decisions then. Got a new Stratocaster in the mail yesterday so gonna be busy. Seeya for awhile until I post pictures of the Faital dash speaker and also a final configuration for those that want to do the dash speaker mod. Keep in mind that mod works with any brand similar speakers. I bought standard resistors to help you all see the layout without my smaller resistor I used. Less words more pictures. See ya soon Atcer2018 and let's keep talking. You've been great.
