I bought these speakers for my car almost a year ago (probably 9 months) and I came back to buy a sub and amp so I figured I'd spend a little time writing a review on my speakers I bought.
I have a 96 nissan 240sx so I had few other options for speakers that would replace the stock speakers well. I have these on a sony xplod head unit 45x4 and they are pretty good.
They do NOT have low end bass though, which is why I finally came back to order a sub. The midrange is great and the highs are pretty sharp. At around 20 on my head unit the speakers no longer get very much louder, but they come close to becoming distorted so it works out quite well.
These are great factory replacements, but probably have less low end than my stock speakers. The mids really pack a punch though and the clarity is good so I would recommend them if you're looking to replace blown speakers for cheap.
They also hold up really well, I listen to my music LOUD so they are quite durable. Fits well in an s14.
