Hello new member from Australia here. This looks like a great forum for CRV owners.
I have just purchased a 2019 CRV and am very happy with the car except that it has a pretty poor audio system. Even the VW Golf I drove prior to this SUV had a reasonable stock system but this one borders on unlistenable at least for extended periods in peak hour traffic.
I have just started installing 2 pairs of Infinity Reference component speakers and have come across this thread. So far I have installed the woofer (using adapter mounts), and the crossover in the passenger door but am struggling as to how to mount the new tweeters as it seems that it will require a lot of modification to the plastic tweeter trim in order to get the new tweeters to mount. You seem to have resolved this issue and I would like to respectfully ask how you managed to do this?
Also were the rear tweeters mounted in a similar way and did you find there was enough room in the rear door to mount the crossover?
Thanks for any advice.
If the Infinity Reference are like the Kappa, the tweeters are a tiny bit too small for the hole - they "spin" around a little bit. This took a bit of trial and error to solve.
First try, I put a bead of silicone caulk around the speaker and shoved it in there, and then put another bead around the outside. That looks like this:
This worked fine for a month or two but my problem was that the speaker didn't stay centered in the mount, it was ever so slightly crooked because the caulk wasn't strong enough.
So, using a similar strategy, I bought weather stripping - here is one that is 1/8" thick
(not sure if this is the EXACT one) and wrapped it around the tweeter. This created a very tight fit that I was able to shove into the stock mount. I did a much cleaner silicone bead the 2nd time and remounted it. This has been there 16 months without a problem, and the same strategy was used in the front and rear.
For the crossover, I was able to find room in the door. I used double sided velcro, and it was mounted against the plastic door liner (sorry, I don't remember exactly where...)
If I end up going back in the doors I'll take some more pictures... a number of folks have questions about crossover mounting.
Good luck and take lots of pictures!
