Conclusion: After hooking these to a marine 4ch amp I was very impressed. They have a good weight to them (big magnets) and clear highs and even put out a lot more bass than I'd have guessed. You should use an amp to drive these a headunit alone will work, but it's night and day. They put my 1990 OEM speakers to shame. Well worth the cost. I also like the white cone and cover, as most boats are white.
Summary: I just installed a third set of these speakers in a 23 foot four winns and i am very pleased. Installation is easy and the sound is grate. I am pushing them with two sony four chanel amps with one 10 inch sony sub. for the money this is a good setup.
Summary: Nice marine speakers. Great sound, affordably priced, easy installation, and good looks. The only thing i would have liked to see included was wiring with the installed ends (20' of speaker wire would be sufficient in most cases). Even though my install was a replacement of existing speakers, i had to modify the terminal ends to fit the Sony's. The small end on the speaker is very small! Other than that, everything works great and i'm happy with the purchase.
Pros: Great looks, great sound, easy install, a perfect replacement for my existing speakers.
Cons: Would like to see some wiring with the terminal ends included in the box.
