I purchased these speakers as factory replacements in the rear of my '08 Frontier. The quality of sound is far better than the factory speakers! They are very crisp and responsive. As other reviewers have stated, there is very little bass output from these. They match well with the 6 x 9's in the front, creating a full sound throughout the cab.

Great product. I am a huge Alpine fan and I was debating on getting these or the type r for a little more money. Decided to go with these since I was adding other type s speakers in my FJ Cruiser. Love the fact that Crutchfield sells the adapters so I could fit these in my 6x9 openings. These speakers really don't provide a lot of bass but that was what I wanted since I added 2 12" Type R Alpine's with a 1200wt amp. The set up right now is perfect with the bass from the subs and the highs and mids from these. Think I made the best decision with I purchased Alpine from my CD player all the way back to my subs.
Great sound quality
I installed these in the rear doors of my 2007 Silverado. The sound is great. It would have been good to have installation instructions, especially with the spacer plates. Once I figured it out the install was smooth. The sound quality is great.
Very easy to install, much easier than Crutchfield led me to believe, however I am very displeased with the performance. I bought these and the component version for my truck. The component version sounds amazing, very clear with alot of bass drive and clear treble. However these were crackling right out of the box at mid-loud volume, possible i could have gotten a bad set. May be returning them very soon and bite the bullet and drill tweeter holes so i can install the component speakers in the rear of my truck.
I replace my factory speakers on my 07 silverado with these alpine speakers. Big sound difference. Can't wait to add an amp to it. I recommend it.
