Soundstage issues

[t1n0m3n 10+ year member]

I think I know what I need to do, but I thought I would run my issues by you guys to double check. I have a 2007 Ford F-250 regular cab truck. I am running a JL Audio 300x4/v2 amp bridged stereo to some JL ZR650 CSi speakers in the door. The tweeters are in the "A" pillar pointing towards the glass.

This replaced some 5x8 Alpine coax speakers that I fried last week.

Let's see if I can describe it:

With the alpines, I could sit up straight in my seat and I could hear the right side way louder than the left side. Soundstage is on the right side. If I lean forward, the soundstage shifts towards the center. Same thing if I lean to the right.... The soundstage shifts back towards center. There seems to be a "bubble" around both the driver and passenger that shifts the soundstage. Now that I have moved the tweeters up to the A pillars, the tweets sound great, the soundstage is perfect, but the midrange seems to still have the "bubble."

Driver's side:

Soundstage right

Move head right or forward, soundstage centers.

Passenger's side

Soundstage left

Move head left or forward, soundstage centers.

Any thoughts?

Speakers level balanced?

Correct acoustic phase?

Whats the difference of the on/off axis degrees of the L/R mids?

Hope you pop that bubble.

"Speakers level balanced?"

The speakers are level balanced with an SPL meter and some generated tones.

"Correct acoustic phase?"

I am not sure what this means.

The speakers are wired correctly though. I have heard out of phase speakers before, and I am not getting any tinniness that usually accompanies an out of phase speaker.

"Whats the difference of the on/off axis degrees of the L/R mids?"

Again, I am not sure what you are asking here.

To me it sounds like I need to have a door pod built and tilt the speaker up and back a couple of degrees toward my head to open up the sound stage. If I sit in the middle, the sound stage is perfect. Of course, this is a guess.
