Good speakers. I got these after not liking the Pioneer TS-G1642R. These have the upgraded driver. Good bass and high are clear. Great stock
replacement in the doors. One thing that crutchfield doesn't tell you when you are replacing speakers and have to use the adaptors. make sure to plug all holes surrounding your speakers. If there are holes in the door that are behind the speaker you will not get any bass out of the speaker. I plugged mine up with some silicone. Easy to put on and easy to take off. I have a 2006 Accord and had to use the adaptors.

Speakers sound great and fit perfectly (2001 Acura Integra). Fronts go in without removing door panel (contrary to instructions). Wiring jumper harnesses make it soooo easy, much better than trying to crimp on new connectors, etc. On the rears however, you must trim the outward mounting tabs for the 6" circle holes, as they interfere with the mounting surround and will not allow the speaker to fit flush. You must also loosen the rear panel to gain access to the speaker (contrary to instructions), which is an Acura problem, not a Crutchfield or Pioneer problem.

I was shopping for rear deck speakers to replace the factory speakers in
my 2005 Buick LeSabre. The Pioneer 6x9 TS-A6962R speakers that I had
ordered did not fit in the speaker wells. My advisor suggested buying
these 6 1/2" speakers with the 142SA69 universal mounting adapters,
instead. The adapters did not fit without doing some significant filing of the
outside edges, but when the speakers were finally installed the sound was
so much better, especially with fade set in favor of the rear of the car and
bass set all the way up on my factory receiver.

Pros:
First off these are three way speakers they are geared towards mids and highs which they produce and they produce very well. The sound quality of these speakers is very good and I bought them so I could actually hear the music with a 15" sub. And wow there is one heck of a difference I would definitely suggest these to someone looking for some clear mid and high range speakers. And before i forget these almost do not distort.

Cons:
I will admit the bass is weaker than what i was expecting and the magnet is considerably bigger than your stock speakers one so be warned when putting these in doors. I had to adjust the door mount a little bit and for some reason on the driver side it intereferes with the window...

These speakers have to be the worst thing i have ever done to my
vehicle. I will give them credit first for the fact that they hit the highs really
well. The bass is practically non-existant. I am not expecting it to hit but i
figured they would keep up with or do better than the stock speakers.
Nope.... A month after I got them all four of the pioneers voice coils blew
out. Now all i have is 4 tweeters and two subs.

Dont Buy!!!!!!

These speakers are amazing. well worth the money. buy buy buy

These speakers are well worth the money. I bought them to replace my front door factory speakers, and they sound a lot better. I was a little worried when I ordered them because some of the reviews said that these speakers weren't that great, but the reviews were wrong. They are great if you are wanting a speaker with crisp sound that hits the highs, mids, and lows well. The main thing to remember is that if you are wanting a speaker that hits the bass hard, then you need to add a subwoofer. I have a Pioneer TS-W301R sub hooked up along with my speakers, and together they sound great. I would recommend others to buy these speakers. They are probably the best thing I have ever bought for 80 dollars, besides my sub.

I bought these to replace the factory front speakers in My 2002 Honda Odyssey. It was somewhat of a gamble since the "outfit my car" says that they would not fit. It was a reasonably easy install. I did have to drill new holes for the screws, but other than that it was 20 minute job.

I wanted an inexpensive solution to improve the low end. These speakers were not as efficient as the factory ones (so they don't quite go as loud), but the low end that was missing, is there finally. (with the factory speakers, the lack of low end would show up on low to moderate volumes while travelling fast, you would really have to turn up the volume to hear anything) I really would rate these 3 1/2 stars, but part of that rating would be due to my factory head unit not being very good, and that the front doors aren't the best location to install these. With a better head unit, these would be 4 stars and a rear deck install, would probably bring them even higher. The new head unit will have to be my next project.

I read the reviews on these speakers before I purchased them. Some people like them and others dont. Hopefully I can clarify this a little. If you are looking to upgrade your entire system with loud speakers and lots of bass, then these MAY not be what you are looking for.
I have a 2002 Firebird with the stock Delco 7 band equalizer stereo. Of course the stock speakers were blown. I wanted to keep the stock stereo for now but upgrade my sound. I purchased these Pioneer 3 way speakers for the rear and the Pioneer 2 way for the front. The bass is punchy and the mids are good with nice crisp highs. The louder you play the stereo, you may need to turn the bass down a little to avoid the flutter but I have found that with any 6.5" speaker.
I chose to go with the 2 ways in the front because I will receive a little more bass with them then I would the 3 ways. The 3 ways have excellent mids, the 2 ways are more high and low. If you accompany the speakers with a small sub or even a 50 - 100 Watt Bazooka tube, you will have an excellent sound system on a low budget. This is not for competition, but will blow the doors off the stock speakers.
For stock replacement or a stereo on a budget, these speakers sound very good. I can play them louder and with more bass then my stock speakers ever could have. One thing GM has done well, is add good bass to their cars. Unfortunately, the stock speakers blow easy because of that.
Remember, these are NOT Boston Acoustics. We are talking about good sound, low budget.

Bought these 6.5's and had them installed today in a 2005 Toyota Matrix, along with updating the Head Unit from stock 6-disc to JVC unit with integrated iPod control.
They replaced the front speakers, and the combo definitely has more snap/punch that I was looking for.
I will probably buy component speakers for the front and put these in the rear in the future - install included disconnection of tweeter in the pillar to avoid potential phase/cracking noise - the soundstage is somewhat less; regardless - the speakers are worthy.
