So finally I got to finish replacing all of the speakers in my 2015 Prius II. Started this "project" almost 5 years ago, but couldnt finish it due to many reasons, one of them being the laziness. I decided to go with Pioneer A-Series for the door speakers and opted for 3" DaytonAudio for the dashboard ones. Now one thing to note that if you are going to go with anything above 2.5" in the dashboard, you will have to do some mods for both of the speakers to fit. I ended up using only one bolt to hold each of the speaker in place but I had to widen the mounting hole to reuse the OEM bolt. Attached are the pictures of the speakers.
Well, seems like some of my pictures are way too large for the forum. So here is link to my Pioneer A-Series Speakers.
