Conclusion: I got these suckas because they were blue and matched the theme of my Nissan and don't let the size fool you! They do put out more bass response than you think! The mids and highs have crystal clarity too, you wont be disappointed.
Summary: These seem to be nice little speakers. I had limited space for speakers in the back of the car so these were the ideal size. The sound is pretty good as long as the volume doesn't over power the speaker.
Summary: My 1990 Toyota Corolla Wagon had blown crappy 4 Inch speakers in front and back. I put these in and added a 8" Bazooka subwoofer. My Sony Deck sounds really good with this inexpensive set up. The speaker quality is really very good considering how inexpensive they are. Unless you're building a $1000+ set up, these will do just fine.
Summary: I am not an audiophile so I can't say that these are great speakers, but for the price they sound really good. They were installed in my son's 92 Lexus LS400 and made a huge improvement over the worn-out factory speakers that were in there. He's happy with them so I am happy iwth them. Easy on the wallet too.
Summary: I recently purchased these with some other Pyle stuff. Out of the 3 Pyle items, these are the only ones that work to what they're advertised. They manage highs and mids very well. They produce good sound, and they're very decently priced. They came with everything needed to install them, including screws. Mix these with a sub, and you've got a pretty decent sounding system.
