Look at the later post, I did not like the Infinitys (too bright, plus they had an unnecessary coaxial structure with another tweeter, for yet more highs which was definitely not needed with the new Infinity tweeters) and sent the front door woofers back for Kickers: https://insideevsforum.com/community/index.php?threads/front-door-speakers.1248/#post-12973 Later, I put the same Kickers in the back doors too, but did not change the tweeters in the back doors. To me the audio was a LOT better, but it never was quite right. Maybe I should have tried to keep the original tweeters with new woofers as a first go (in the past for other cars, the improvement was the other way, changing the tweeters first), or looked more carefully at woofer/tweeter pairs (individual woofers and tweeters designed to be used together). One problem is that the dedicated pairs most commonly need a separate speaker wire from the door to the pillar for a crossover in the door. A few mount the crossover with the tweeter in the pillar, for those without the door to pillar wires. For example, the Audison Prima system sounded pretty good in a Gen 1 Volt (separate crossovers for each tweeter that mount in the pillar). Of course to some extent, the radio itself, and any internal crossovers in the head unit before the wires to the individual speakers, might limit what can be achieved.
