I spent the afternoon making some changes to the boat, including beginning the process of installing mid cabin speakers. Since I was hoping to install them in the mid cabin inserts I spent a long time measuring and checking depths before I drilled a 5" hole. My first step was to remove the cup holder near where I wanted to install the speaker and measured the depth to the outer wall. This measurement scared the crap out of me as it was about 3" to the edge of the cupholder to the out hull wall and there was about 1" between the cupholder and the insert wall (so only 2" of speaker clearance).
Not convinced yet, I removed part of the wall in the changing room and took some measurements there. These measurements showed there was 3.5" of clearance (the cupholder is much lower...so the clearance is less)
Since I could see behind the coving from this vantage point, I could see that there was likely enough room, so I took the advice someone earlier in this thread suggested and I drilled a tiny hole and stuck a wire in there. This measurement also read at 3.5".
I could also see where the wire came through from the storage closet view, and my only concern was one of the longer screws through the rub rail, so I attempted to mount the speaker as high as I could to avoid the rub rail more. At this point I decided to take the plunge as the JLs I was planning on installing needed 2 7/8 depth. So out came the hole saw and drilling began! Once I was through, of course one of the screws was very close to the back of the speaker....so I cut it off.
Here you can see the distance to the screw:
After this, I test fit the speaker again, and all looked good!
So I finished installing the speaker and here is the end result:
I'm very happy with the results, and now just need to go through the same process for the other side. Of course I will likely double and triple check the clearances on the other side as well! And the dealer said it wouldn't fit!
I'm waiting for wire to arrive to connect the Wetsounds amp then I'll know how they sound!
