Summary: I put four of these speakers in my 2014 Mustang. These speakers are awesome. I have these speakers wired up through my stock stereo, not using any amp. I would recommend these speakers to anyone wanting to get a better quality sound.
Conclusion: I bought these for the rear of my '02 F-250 (Crew Cab) and have had them for a few months. These fit the factory location, but I did have to drill a few holes, the mounting holes did not line-up perfectly with the factory holes. My rear seats partially block the speakers, but the sound is still acceptable. The highs are great, but these don't get quite as low as I expected. I thought that they would cover the low end a bit more than they do.
Conclusion: Speakers cover a broad range. It is a great speaker for the price. I have four of them in a focus as a gift for my wife. I would definitely recommend adding a sub though! I'm using two polk dbl 10s with an older 6 channel soundstream amp. Just make sure you have a good deck! I have a Sony GT620IP (I think) that makes the highs almost too much with the DSPs and different music makes adjustments necessary.
Conclusion: These are good speakers for the money. They are a little above entry level, but regardless sound good. I don't know if they can take 75 watts RMS though. I have them hooked to my Alpine KTP-445U, which is 45 watts RMS to four channels, and I can't turn the gain up past about half without hearing distortion. But with a small amp, these speakers sound good. I would recommend them.
