I finally got tired of sitting directly under one of the speakers in my '70
Caravel. Been thinking of moving them toward the closet or fridge for years. The bolt of intuition hit me just this weekend--HEY!, there's plenty of room behind the fiberglass dome on either side of the control panel. I mean, like plenty. The speaker is only 3.5" deep behind the face of the panel and there is about 7" depth there. This is a moderately robust 7x9" speaker.
I felt around and it appeared there were no wires or structure to interfere, so out comes the pencil and saber saw. Wack--the first one goes in easy.
Not so the second one. The TV charging wire comes up on the curb side of the windows and excess wire is curled around randomly behind the fiberglass. Whip, zip, cut that sucker in half. The cut was at a point that gave me a few inches of blue wire, just enough to get a wire nut on it and splice the ends back together. You can just see the red wire where it's attached to the blue--the red goes over the ceiling to the back end.
The finished product is on the right, with the door to the bookcase open. I like this box--with only four screws all the interior dividers come out and can be reconfigured. In addition, the whole box comes out of the overhead with only four screws.
They sound much better when standing in the kitchen or in the back--true stereo. And it's way more comfortable sitting at the table. The speakers are about one more foot away from your ears and not pointed so directly at them.
I could have taken the control panel cover off (as you can see, it's a prototype for later instruments) and reached inside to check behind the new hole, but it appeared that the power wires went "down", not "across". Oh, well, not too much harm done.
