I'm def interested to see how this turns out. I have a non-JBL system and I put some JBL's into the fronts and I just need to get my hands on another JBL rear to replace those. The tweeters are the only thing I have neglected. However I do have an amp driving all the speakers and audio is way more complex then it appears at face value! I don't even know where to start with tweeters. All I know is that I got some infiniti speakers and the rubber connectors to the cones blew, hence my "upgrade" to JBL with the all paper cones connected via fabric/weave.

They are actually the stock JBL's, I ran across a 2012 RAV4 limited in the junkyard and I couldn't help myself. Unfortunately, someone had already taken one of the rear doors and the subwoofer, hence my incomplete set. I also neglected to take the tweeters, oh well. So anyways, the fronts are component and I believe the non-JBL speakers are wired in parallel w/ the tweeters. I'm in the process of investigating options for the tweeters. My speaker amp is an alpine mid-grade but is only a 4 channel capable of 4 ohm. I should prob upgrade to a 2 ohm since that is what stock JBL's are rated for? Right now I have no issues with volume or clarity, I'm unsure if a 4 ohm amp on 2 ohm speakers is destructive. I have heard people say that the stock JBL's are bass heavy and to compensate for that I have turned the high pass filter to like 180 or something to keep the bass at a minimum. Perhaps I am handicapping my system, I don't know, I am a total newb when it comes to audio.

That's very clean! The real reason why I got the 12 year old speakers is because I had 2 speakers that I had installed in 2018 that their rubber surrounds had cracked. Ideally, your right, I'd def be better off getting new speakers. But for now, I'm a cheapskate and I'm gonna see how long these speakers go. They are definitely more robust in their construction than most aftermarket unless you are looking to spend hundreds per pair of speaker. They are in fact OEM JBL's with Toyota part #'s on them, my guess is that the junkyard put the wrong year on their listing. I didn't actually look at the production date. But if they are 2011's that just makes them just as old as my tweeters hah.

I really need to take the time to clean up my install. I was very careful with all the wires and not scrimping, but the powered sub is underneath the front passenger seat and I think I would rather do your method and route cables under the carpet and put the sub under the rear seats. I know some people have gone so far as to mount a sub in the OEM spot, but I don't know if I want to go to that effort. But as far as the amp, mine is in the exact same spot as yours is. Believe it or not, I actually got the next generation of Amp that you got, MRV-F300.

Regarding the brackets, I have a 3D printer myself and would love an opportunity to print something useful for the car rather than constantly printing new fidget spinners for the infant haha.

How did you determine which parts were and were not loud? I def like the idea of not doing the scorched earth method of putting sound deadening. I’m just curious. How much matting did you end up needing? If nothing else, I’ve wanted to dynomat the floor for quite some time so that my commute to and from work is more tolerable.

also, would you be willing to share the stl for $free.99? I understand if not though.

Um, is there such a thing as bots in these forums?

I'm hoping to get them too, my tweeters are at the end of their life lol.
