Conclusion: These door speakers are great,especially when paired with a Kicker 200.4 amplifier (50 watts per channel at 2 ohms). The speakers are rated at 40 w RMS, so I followed the advice i was given by a pro installer. Make sure the amp is about 10 watts RMS more than the rms handling of the speakers. We can always turn down the gain. My installer told me that if you are on a budget, go with Kicker or Alpine ONLY.
Conclusion: 2010 regular cab GMC needed a more than just a radio. Put these in the doors to replace factory speakersthat were totaly dead. Too many choices out there, figured Alpine was as good a choice as any. Another gut call that went well. Very nice sound!!

Conclusion: Really surprised by these speakers (used to do a lot of custom car audio). I bought them locally at a Boxing Day sale after I heard them. Picked up two sets for my winter beater and they sound absolutely fantastic with my Pioneer DEH-X8500BS head unit. It's not often a cheap set of speakers can sound this good. Impressed!
