Summary: Put these speakers in to replace the OEM dash speakers on a 2003 Jeep Wrangler Rubicon which were starting to sound a little raspy. They are a solid replacement, very easy to install, and as always, the adapters and instructions from Crutchfield were outstanding.
Summary: I ordered these speakers to replace the 10 year old speakers in my Eurovan. They are clearer and crisper, but the base is lacking. Dialing up base and loudness on the stereo helps some, but the speakers start distorting before the sound becomes satisfying.
Summary: I needed a 4 inch set of speakers for the rear end of my FJ Cruiser. I was expecting these to sound good but not this good. These speakers really helped fill out the sound in the truck and are well worth the money.
Summary: Paired these with the Pioneer TS-A1305C and Pioneer receiver. Good overall sound. Of course could use a sub but fine without. Fit in rear of my 2000 Silverado 1500 but needed more hardware than came with adapters.
Conclusion: I have them in my 99 grand prix with a 4 channel pioneer amp and they sound really good. The clarity is excellent. I replaced my older pioneer head unit with the deh-x9500bhs and it seems that the clarity went up even more. These are some really nice speakers.
Conclusion: I got theses speakers just 3 days ago and i am amazed by the highs and lows! First of all they are built extremely strong, when i was drilling holes for the speakers the drill slipped onto the speaker and there was not even a scuff!
Conclusion: Installed them in a 1988 Toyota pickup truck. There just isn't any easy way to install a full size speaker in this model truck. Only has a place for 4" speakers in the lower dashboard area. There is no enclosure so the bass isn't strong but from the mid-bass up, these speakers are top notch.
Summary: I installed these in my 2002 Porsche 996 Cabriolet as a direct replacement for the dash and rear factory speakers. I considered the Focal 100CA but the Focals mounted too deep for the rears. The Pioneers are a steal at this price and their performance is terrific.
