I recently installed a pair of Kicker ks 6 1/2 speakers in my civic and was shocked at how bad they sounded with an Alpine head unit. Today, I pulled them out and installed a pair of these Alpines and they are a lot more musical. I would have rated them 5 star but I feel that they may lack in the low end but sound great for mids and highs. I'm using a sub for lows so the bass output wasn't important to me. They are much better than the Kickers when powered from a head unit only which surprised me due to the Kickers higher spl.

Bought these a few weeks ago. I was able to listen to them at a local store and compared to all the others, the Alpines have smoother highs and tighter bass. They do need more power than many of the other brands but it's worth it. Definitely for those who prefer quality over quantity.
Great speakers for a good price
I have these speakers paired with an Alpine SPS 610c system in the front, powered by a 4 channel alpine amp. They sound great, can produce solid bass, with nice highs. The Crutchfield fitment guide said they would not fit in my 1999 Dodge Durango SLT, however, they fit perfectly.

quite a nice upgrade for stock rear door sliverado speakers, handles the power from an amp very nicely i would very highly recommend anyone to upgrade 5 1/4 size to these!
