If your taping the holes and not using self taping screws it may be a good idea to run a small bead of blue or lesser grade loc-tite on the threads, just don't use red. Or use a lock washer on the screw, the reason this is, is if a hole is just tapped and a bolt inserted it can possibly back out from vibration and weight of the speakers, make sure to use premium ss bolts/screws as well.
Its looking good, an fyi a fish tape makes running wires on a boat a breeze. On my 22' Mako it is real easy as all wire runs are pre fab through pvc pipe in the hulls anotherwards you just push the wire through and small wires you use a fish tape.
Another fyi you can buy pods for the back of the speakers, 6", 6 1/2", 6x9's and so on it makes them sort of a box and you will be amazed at how much bass and mid bass you can get from 6 1/2's and 6x9's. I'm running 6 - 8" full range memphis speakers on my build, 1 12" sub and tower speakers on the t-top.
I will post up a full detailed post/thread on the build once the hull restore is completed!
