I couldn't seem to find any info about tweeter upgrades in the 3rd gen so I figured I'd post this here for anyone that might be interested. The easy route would've been to cut a hole into the grille for a flush mount, or surface mounting it, but I wanted to keep a completely stock look. Let's get started!
From the service manual, the dash grilles come out by prying up from the front edge where they're mounted with plastic clips. A trim removal tool would be ideal but a screwdriver with a rag or some tape will suffice. Once they're out, you'll need to unplug it from the wiring harness. Surprisingly, the tweeters are actually angled toward you rather than just blasting into the windshield like other cars. The tweeters themselves are clipped into the grille and they have a circular opening with a cutout for the connector/capacitor part.

The stock tweeter is a 1 inch tweeter while the body/grille opening measures roughly 1.5 inches. Honda uses this same tweeter in several different models as well.
You'll need to do your research to see if your desired tweeter will physically fit into the opening. My weapon of choice is the 3/4 inch Infinity Primus 753T since it's quite small and I figured the cylindrical shape would make it easier to mount (and I have a bit of a brand loyalty). I ended up using the included surface mount and a layer of foam tape as a spacer to make it a snug fit as you'll see in the next photos. The tweeters were then hot glued into place.

Last but not least, wiring. I don't like cutting into factory wires unless I absolutely have to. Luckily a brand called RED WOLF makes tweeter wire adapters for many different vehicles. Not even Crutchfield carries these. This one is compatible with our 3rd gen and it's what I'll be using in this guide. The adapters come with standard speaker connectors on the other end but unless you have the correct ones on hand, you will have to snip them off to splice to the tweeter crossover. Something I noticed with these adapters is that they are actually labelled backwards from what the FSM wiring diagram states. I don't think the polarity on tweeters matter very much but it didn't sit right with me so I flipped the wires around when splicing.

^ Correct polarity
Once that's all said and done, you'll end up with something like this:

Thanks to all our hard work, we can now install it just like the factory tweeter by plugging it in and snapping it back into place.
Now for the ultimate question: how does it sound? In one word, incredible.
I have sound deadening and Infinity Primus PR6512IS speakers in the doors, as well as a Rockville SS8P compact subwoofer under the passenger seat but the weakest link was the tweeters. No amount of EQing could get rid of the harshness and muddiness of the stock Honda tweeters. These new tweeters sound so much crisper and clearer which was exactly what I was looking for to make the daily commutes that much more enjoyable.
Conclusion: If you're still rocking the original speakers and looking for a cost effective upgrade to your audio, I highly recommend starting with the tweeters.
