Conclusion: Bought these to replace Jensen speakers in our boat. The Jensen speakers were excellent speakers and held up fine, they lasted five years but finally gave up here on the coast. The Kenwood speakers sound great and were not as expensive. Can't say as to how they will hold up yet. Also, I don't like the other flashy chrome looking speakers, these are white and don't stand out against the boat. Very pleased with these so far.
Summary: These speakers are replacements for some JBLs that were installed, which one was blown. Install was simple as the holes and wires were already there for me. These do not come with speaker wire, so be aware when ordering, not a big deal to me, as mentioned, the wire was already ran. These sound pretty good, as they are the only speakers in the boat and I am only running them from my deck, no amp.
Conclusion: I have used these in two pontoons and one ski boat now. I have never been disappointed with their performance and that is why I continue to use them in my new watercraft. Highly recommended.
