Completely useless tweeters did not work. Come on Honda, really? I am of the opinion that Honda puts tweeters in the Ridgeline Sport trim only so that customers who seek quality sound will have a molded in location to put the aftermarket upgraded component speaker tweeters. It is certainly not to have any functional sound emit from those factory tweeters. I put a listening isolation tube up to the tweeters. (vac hose) No sound ever emitted from the tweeters. (doors opened is huge help for isolation hearing)

I scheduled a warranty repair. The service manager demonstrated via the test mode (push 1 & 6 then on buttons) that each speaker in turn did in fact sound off indicating that they were working. And my listening tube verified the sound came from the tweeter. The conclusion being that my system was working, He pointed out that this was the not so great performing base trim 200 watt system. I have since concluded that the test mode is there to verify all the wiring was successfully assembled but is not an indication of the usability of factory installed tweeters.

The quality of the factory tweeters are so pathetic that all they ever emit is the test tone and some super high useless frequency and or any useful frequencies emitted are rendered so poorly that they might as well be non existent.

I replaced them with $16.00 tweeters off Amazon and the problem is solved. Come on Honda, really?

I also replaced the door speakers for $90 total for a huge improvement.

Honda spends pennies on speakers, not dollars.
