Just a quick update FWIW, after some time, I found the Infinity door speakers too bright.
After more discussions with Crutchfield, now trying this speaker:
Kicker 44KSC6704 6-3/4" 2-way Speakers
First impressions are much better bass and midrange in comparison to the high end. Also, the sound settings seem to be more useful now to fine tune the three ranges.
Still less performance than if an amp and maybe even sub woofer were installed, but many times better than the stock speakers.
