How do these preform in sealed box in boat applacation. Would you recomend them?Thay look to be a good sub from what i have read.Just not seen many in boats?

Love mine, it pounds in a very small enclosure.

I have a 15" in our boat and it hits very hard

Great subs love mine.

I only have a 10" and it bumps. My box is ported though.

I have a sealed 12" sounds great.

Sealed 12 in mine and love it! It hit really hard if you throw some watts behind it. I'm pushing it with a kicker zx 500.1 and honestly on glass days if we are sitting still you can see the ripples in the water from it hitting. For the price you can't beat it IMO. I get complements everytime we go out on how good it sounds.
