Summary: I purchased these to replace the factory speakers in my Chevy Cobalt that had gone out. They are acceptable with no surprises - bass is not as low as factory, high end is pretty clear but nothing to write home about. Buy these for a cheap replacement, but don't expect to be wowed by them.
Pros: Low cost, clear high end
Cons: Poor bass, other better speakers are not too much more expensive
Summary: Installed these speakers in 2005 GMC Sierra- they rejuvenated my factory stereo- Installation was a snap with instructions and supplied parts. Shipping was incredibly fast. Good Job Crutchfield!
Summary: I think these door speakers are good for your back doors because not a lot of bass comes from these. They are great for mids and highs though. I have played many types of music on these and the all sound crisp and clear. I personally think they sound great for rock songs and most rap.
Summary: Overall I'm pretty happy with this purchase. The speakers provide plenty of good clear sound. If I had it to do over again, I would have chosen a larger speaker to pick up a little more low end. As far as the Crutchfield Mastersheet goes, it should provide more detail around clip placement and panel removal. I ended up calling the help desk who was very helpful in providing more detail.
Summary: Sound quality is very good, far better than the factory speakers. Real good mid range sound, and excellent high range sound. Bass is as expected for a 5 1/4". Overall very good speaker. The only down fall is the mounting holes. They just didn't come close to being an "exact fit" as described.
