Well it was too easy to feed wires from tweeters to head unit. And they made a big difference, I can hear the symbols and other high notes I was missing. And the boss tweeters were only $15 so well worth the investment. I made a topic with pictures for those interested .It is extremely doubtful there is any wiring for the dash tweeters in the base models. This is from experience in other Hondas. In fact, most folks looking to upgrade even models with the tweeters skip changing them. Just not worth it.
