Summary: Good, solid, middle of the road speakers. I purchased two sets of these; one set to liven up the front stage of our Altima and the other set to replace blown mids in the front doors of our C240 wagon. On the Altima I also replaced the head-unit with a Kenwood Exceleon KDC-X598 and sound deadened the crap out of the doors. I have not added an amp at this time and only notice clipping at higher listening volumes.
Clean clear sound, great is for those who are not just looking for bass

Summary: Great clean sound, people who install this speaker set need to be aware that in order to take advantage of these speakers output, you will need an amp, otherwise the base will seem sub par. I installed these with my stock stereo, and the sound quality is miles above what I was getting from the stock speakers in my Silverado, even with out the amp. I would recommend these. Sound quality is crisp and clean.
