Not sure if i got the wrong hardware or if the hardware isn't stainless or made for the salt water environment but 2 days on the water here in south carolina and this is what it looks like a week later
Had to replace 4 factory 6.5 Kenwoods, other than enlarging enclosure with a cut out saw, everything went seamless. They sound pretty good, still trying to tune up alpine MRP-F300 amp or if I need to upgrade to the 500 or 1000w. Hope to eventually add the 8 inchers down the road
Replaced blown out 6.5” speakers, decent bass, real clear. Dimensions a little bigger than other 6.5” speakers I removed, with a small amount of trimming to original hole fit just right.
