In his install yes they sound good, and he probably beat a lot of other higher priced speakers in process. They also sound pretty good in Shadow's install. I never said Kicker's sucked; not sure what you are implying....I actually had them in some Titan Tower Speakers....they sounded nice, but they were also no comparison in the tower setup vs. the NVS.
Actually listen to the Kicker coaxials compared to the other speakers in its price range. They are not the best sounding for the money. They do the job becasue of how LOUD the boat is but as far as actual sound quality they are very low on the list.
