Awesome quality!

I would recommend this product to anyone. I have an FJ Cruiser and i replaced my stock 2' speakers in the front and rear of the car. The sound quality is superb compared to the stocks. I just recently bought a pioneer double-din system which brings out the rich crisp sounds from these speakers. They hit the highs well and still give off a good amount of mid range sounds.

These tiny speakers will get loud. The tweeters are outstanding. I had the radio on 60 and they sounded great with no distortion. Easy mounting process in a 84 Chevrolet which was very helpful. I would recommend this product and website to anyone.

The sound was great after a very tough installation! Going into a 1986 Monte Carlo SS Dash. They were the only speakers you could get into this dash board (barely). But it was worth the time and money. Nice crisp sound for speakers!!!

Surprisingly good speakers for not much $$$$

About 5 years ago I replaced the factory speakers in my 02 Envoy with Infinity reference speakers. The truck has the factory Bose system which sounded very nice, but I knew it could sound better with some aftermarket speakers. The Infinity's were a great upgrade and fit my budget, although I find them to be too bright. About 6 months ago one of the dash speakers developed a rattle, and I decided to replace them. After doing a bunch of research - and reading reviews, I decided to try the Pioneer TS-A878. I figured if they weren't any good I'd be out less than $50, so what-the-heck. At first I was a little disappointed because the speakers sounded flat, but then I played with the stereo's equalizer and WOW the speakers came alive! The lower mids and midrange sounds great, with voices and guitars sounding very clear. The soundstage has nice depth and I hear things in the music I didn't hear before. I like these speaker so much that I plan on replacing the Infinity reference components in the rear door with Pioneer components sometime in the near future.
In conclusion, I couldn't be happier and feel these speakers are MUCH better than their $45 price would let you to believe. Maybe more expensive speaker would sound better but I like getting value from the things I buy, and these speakers hit the mark for me. They sound GREAT! I've only had them 6 months so I really can't comment on their long term durability, but so far I haven't had a single problem even when driving them hard so I gave them 5 stars.

What a speakers!

The reason why I bought these speakers are the reviews. Boy, they were right. I'm hearing music instruments that weren't present in my stock speakers. It has good detail, the mids were improved and the highs are crisp but not too bright. Most of all, it raises my soundstage big time. The crashes of the cymbals were so distinct, and the vocals are clearer than my stock speakers. I even know some of the lyrics on Van Halen's I'll Wait and Jimi Hendrix's Foxy Lady. These little magics are powered by a pioneer DEH-6300UB head unit. I have Kicker speaker up front, Rockford Fosgate in the rear and Sound Ordnance sub to complete my system. Don't be fooled by its low price. These are one of the best bang for the buck speakers! Couldn't be happier!

Good replacement front speakers for my 87 monte carlo ss restoration project...Although i did wait until i replaced the windshield to install them..... Not enough room between the dash & windshield to squeeze them in with out breaking something...Much easier to work with the windshield installer..They pulled the glass & allowed me to install the speakers at their shop before installing the new windshield
