I'm planning on getting a set of 6 1/2" components, but since they are so expensive I would like to get some expert advice from peeps out there on the best 6 1/2" components for the buck before I go ahead and spend my whole month's pay check on some very expensive components that I have no feedback on. I am looking for a component that has very good sound quality if not the best and high RMS for the buck. I am looking into the following components and please feel free to give me your expert advice and any recommendations on others not listed would be appreciated.
1. Infinity Kappa Perfect 6.1
2. Kenwood KFC-XR61p
3. MB Quart QSD216
4. MB Quart QM218.61Q
5. Polk Audio MM465 MOMO series
6. Boston Acoustics ProSeries 6.5
7. Diamond Audio S6.0mx3
8. Diamond Audio S600a / S600s
Please give me your feedback on which is the best for the buck out of all of these components. If there are any better 6 1/2" components then these please let me know. I would also like to know what amp would be best to use for the 6 1/2" component?
