Review: 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.
Review: 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.desertcart.com/gp/product/B00H3RL6NI/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

## Questions & Answers

**Q: What about dept!!!**
A: The top-mount depth is 1 7/16 inches.  The bottom-mount depth is 1 9/16 inches. The cutout diameter is 3 1/16 inches.  Thank you for the question.

**Q: Does it fit in a 07 crewmax toyota tundra**
A: It could possibly. The TS-A878 has a top-mount depth is 1 7/16 inches, bottom-mount depth is 1 9/16 inches, cutout diameter is 3 1/16 inches. According to Scosche, the 2007 Crewmax has the following dash opening dimensions: L: 3.16" W: 3.16" D: 1.35". The Scosche website was cdn.scosche.com/media/guides/ta1041.pdf.  According to specs, the pioneer speaker depth is slightly greater than the Tundra mount depth, but you may be able to do a little cutting, or sanding to obtain the additional space. If you can, remove the old speaker so you can obtain a preliminary look to get a better idea of your options. I hope this was helpful and thanks for the question.

**Q: what is the depth of the speaker, from face to back of speaker?**
A: These speakers are just under 2 inches from the bottom of the magnet to the top of the cone.

**Q: Will these speakers fit a 1996 Chrysler Sebring Convertible?**
A: No, these speakers are mainly for older vehicles that have "in dash speakers".  You need 6 x 9's for both the door speakers and rear.

### ⭐⭐⭐⭐⭐ Good back for the buck
*by M***S on July 16, 2020*

### ⭐⭐⭐⭐⭐ Pioneer!
*by M***O on September 3, 2019*

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.
