Conclusion: The alpine speakers sound great. They handle the power very well. They are great for the boat, and fill the boat with good solid sound. I have two in my 20' flats boat, and the sound radiates the dock.
Summary: So, like others, I picked up these speakers after reading the few, mostly positive reviews on various sites. I compared these with the 6.5" version, the JL MX650, the Infinitys and the other popular brands of boat speakers and ultimately decided on these for a couple of reasons. They were slightly larger than the 6.5" standards, which I thought would produce more bass off my stock Sony CDX-H910UI deck.
Summary: I built a little bench in between my back seats of the boat to fit these. I turned on the deck and immediately impressed! The highs are nice and clear and the bass is really impressive for a 7" speaker. My wife can hear me coming to our camping spot a from ways away. So far I just have 2 of these powered by a JBL 20 wart RMS deck. Planning on an amp and 2 more next year to be making waves in the lake from these impressive speakers.
Summary: Best bang for your buck in my opinion. Similar JL speakers that I was looking at were three times as much money. I've had pioneer, Kenwood, and kicker speakers and these are by far the best. Also, make sure to go for the 7" over the 6.5". I have both in my boat and the 7" sound noticably better.
Summary: I got these speakers after doing a lot of research on marine speakers.The Alpines were rated as the best sound for the price. I installed them on Sat and took out the boat thinking these would be very loud.I was extremely disappointed. They are no better then the factory speakers I had previously.They were in-expensive and I just thought they were going to be better.This review is no reflection on the seller. They were great.I would give them a "c" grade at best!
Summary: I bought a pair of these a year ago for my boat. These speakers made me th DJ of party cove lol. My system will over sound anyone else's on the water. Cannot believe the sound and how loud they can get.
Pros: Sound quality at high volume Ability to hear at a distance clear ( off the boat and in the water many boats away) Cost
