I knew this would come again so here we go. My cutouts for the cabin speakers are 6" holes. Running 6.5" speakers has been a bit tricky to mount. I basically had to have another ring under the back side of the hull and 'clamp' the speakers to the hull with mounting screws.

Been looking around a little and so far the closest option is the JL7.7's needing an opening size of 6.25" - I could probably make that work.

Anyone know of any other larger sizes that take around 6" opening? The less cutting or fabricating of adapters the better.
