I installed these in the front doors of my 1995 Mazda 626 to replace the stock speakers. This is my first pair of speakers, so all I have to compare them with are the factory speakers.

Let me start by saying that I am completely amazed by the way these sound. They are just incredible. I installed them along with a Pioneer DEH P3000IB receiver. I don't have my system amped, but the HU puts out plenty of power to these.

These speakers are noticeably quieter than the factory speakers that I have installed in the rear. I've adjusted the balance so that it's not an issue, though. If I don't, the rears over-power them, and mud-up the music. For the first time in my life, I've set the EQ to something besides pure bass. I set the EQ on vocal so that the mids and highs really come to life. I've never listened to the lyrics before. The human voice has never sounded so good. Enya sounds as if she's right in front of me.

I'm somewhat disappointed with the bass that these guys put out. It just sounds like dull 'thwups'. My factory paper speakers have a ton more bass in the rear than these do. But it's okay, and everything balances out. It sounds absolutely great, and my parents and friends have said the same.

I highly recommend these speakers. I'm sure that there are others that sound better out there, but I doubt that a normal human would be able to tell the difference. I think that if I turned these up loud enough, I could hear the lead vocalist blinking.

I replaced them three times already, had them on a cadillac CTS, took them
out, one was blown, put them in a RX8, with a new pair, returned from the
factory. They blown again. I dont recommend them.

Ive had these speakers for about a year and now i wouldnt put any other brand of speaker in my car. The mids and highs are incredibly clear and full even at the highest volumes i can take. I have the pair in the sound bar of my Jeep Wrangler and all you Jeep guys know that its near impossible to hear anything at speed but when i put these in after trying Pioneer and MTX, this set can handle anything from light acoustic to heavy rock at extreme volumes for long periods of time. If you like it loud and clear... this is the set for you. Well worth the buy.

These speakers sound clean! I've had them about 3 months now and I'm very pleased with their performance with my stock head unit. However, the head unit is a JBL and it has a small amp in the dash, so that's probably why they are working well. I put them in with my old sub and amped the sub--doing this project piece by piece. They sound so good, I can't wait to get them properly amped.
If you like clean full sound, this is a great speaker.

Don't bother using these with your OEM stereo equipment, they will break up at anything over half volume. These guys need some power to operate properly. They are overly crisp for my taste.
