Hey guys. Here's my idea. I need to get through the hardwood on the built in bookcase and 5 or so inches of drywall to access a side of my tank. I want to use 2 mp60's on this end of the tank. So many questions. Will a stud finder work through solid wood? If I drill out 2 5 inch holes with a hole saw, can I the somehow create a plug of sorts with the drilled out wood and a grommet type thing to cosmetically mask the holes? I should be able to drill through the wood and the drywall without damaging the tank right? I'm nervous about screwing up the wood on the bookcase and invoking the wrath of my wife. Thanks aquatic homies.
