Ima recommend these till I die
Awesome sound quality and brightness. Nice looking and good value. I would take these over any other in this price range. I got silly and got ones from kicker, those let me down. Had to come here and share my feeling on how good these are.

Good back for the buck
I've long since upgrade the sound system on my 2006 PT Cruiser. Did a 6x9 conversion all round, have 2 amps and a sub. Never got around to doing the tweeters. But I soon tired of the horrific high pitch from the stock pieces of junk when the volume was cranked. No surprise when I examined my tweeters how poor of a condition they were in. I gently touched the cone, and it cracked like old paint. Not good. I pulled the stock ones, and used a 9v battery to determine the positive and negative poles on the stock wire connector. (You can use a 9v square battery on the contacts of a speaker to determine polarity - If the cone pushes out, you have the correct orientation. If it goes down, flip your polarity). Once I had this figured out, I wired in an additional capacitor. My amp pushes out a good deal of power, and without reducing the bass it would tear these to pieces. I will link what I used below. Once wiring and fitting was complete, I had to adjust my Equalizer due to the change in frequency at the front end. But once I dialled it in, it sounds amazing. Significantly better than the awful sound quality from before. And it's a little louder, and these will be more durable long term. I did not have to trim or cut up my dash, they just fitted. I got rid of the star screws my dash came with, and used the supplied cross screws from this kit to make things easier. If you're considering replacing your dash speakers, you should buy these. If you are replacing dash TWEETERS, you WILL NEED a capacitor or you will trash your speakers. Here is the cap I used: https://www.amazon.com/gp/product/B00H3RL6NI/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

Pioneer!
So, I have a 2019 RAM 1500 Big Horn "Classic" crew cab, and I knew instantly that the factory "Paper" speakers were going to come out of it. They sound so muffled with no life in them at all. I had already replaced the 4 door speakers with Pioneer TS-G690 6x9 speakers that fit perfectly in the doors with no modifications at all. Those speakers sound great BTW, but now it was time to upgrade the two 3.5" dash speakers. I like to keep the same brand speakers all around a vehicle if at all possible. I found these Pioneer TS-A878 3.5" speakers right here on Amazon for a great price! Amazon said they wouldn't fit my truck, but oh how wrong they were. I took the chance and bought them. They went right into the factory speaker hole and the factory screw holes lined right up with these speakers! They sound so good with the Pioneer 6x9's in the doors! I highly suggest using metra speaker wiring harnesses to plug right into you factory speaker plug. The Metra number is 72-7902. I know for a fact you can get that harness at Crutchfield.com if you can't find it on Amazon. If you are looking to upgrade your factory speakers on a Ram truck from 2012 up to the 2019 "Classic" these Pioneer 3.5's and the Pioneer 6x9's are a GREAT choice! I'd also like to add that I did install 600Hz bass blockers with these speakers as well. You don't want a lot of bass going to a speaker this size.

Fits 2008 Chrysler Town & Country
Bought and installed these in a 2008 Chrysler Town & Country. They fit with no modifications. Sound is so much better than the little 2.5" speakers installed from the factory. The standard Metra wiring harness was too big which required me to splice into the factory wiring (Left side Grey/Violet +, Right side Green/Violet +).

They fit
These pioneer speakers went right into the dash like factory and sound even better.

Perfect fit
for the center channel on a '18 Ford Edge. Upgraded the factory sound and my Kappas in the doors were butchering the high end. I find tweeter separates too harsh for my ears so this single center channel speaker helps with the highs so I can remove them from the door speakers.

Great sound and fits Ford F150 Center, Dash speaker.
This will fit a 2021 Ford F150 Center, Dash speaker. A great upgrade sounds great. The magnet is 10 times bigger than the old factory speaker.

Excellent speakers!
These speakers are incredible. I needed to replace the speakers in my 1999 Dodge Ram Wagon (full size van). Only 2 of the 6 speakers were working. The factory setup is 3.5's on each side of the dash, 6x9's in the front doors, and 6x9's in the rear panels. I used Mopar replacements for the 6x9's, but could not find discount priced Mopar 3.5's for immediate sale, so I researched the aftermarkets reading reviews and narrowed down to these, as I wanted lower priced speakers. Anyone can spend 100+ bucks on 3.5's but I wanted the best bang for the (low) buck. Now, after hearing the 3.5's, I honestly wish I had replaced ALL my 6x9's with this line of speakers from Pioneer. The 3.5's in the dash absolute scream in comparison with the Mopar factory speakers -- the Pioneers are incredibly efficient, clean, and project extremely well! As stated in other reviews, they do produce some nice bass tones -- not enough to stand alone (unless they had to) -- but definitely a nice complement to full system. As a value conscious person who only likes the best, I highly recommend these speakers. I will be using speakers from this Pioneer line for my other vehicle. I'm a working drummer and use this van to haul my equipment and I will not compromise on sound quality. I feel that these speakers do an excellent job of reproducing music the way I like to hear it. They are a real winner in my book: excellent sound and low price. Now lets hope they last!

サーブカブリオレのダッシュボードに装着!
元々音質にはそんなに不満はなかったのですが、 さらに良くなればということで購入。 配線は少し加工が必要でしたがあとはポン付けでOKでした(°∀°) ツイーターも一緒に変えたのもありますが更に音質が良くなって満足です!(°∀°) ドアパネルのスピーカーも変えようと思いましたが、 しばらくはこの音で楽しみたいと思います('∀` )

Fits well in an old Miata's headrests
No trimming, good fit in the headrests of a 1990 Miata. Miles above the factory paper speakers. Not much in the realm for base, but the high's and mid's make the sound from the only two door speakers come alive. Can hear them very well with the top down, still clear. Easy to install.
