Step 2: Diagram

  • I first measured out where I wanted to place the speakers using the ruler or a tape measure.

  • I measured out the centre of the guitar and drew a centre line parallel to the guitar neck (see picture). I then used a math compass to draw the circles to be cut out.

  • Note: Make sure when drawing the circles to give the speakers enough distance from each other.

  • I suggest drawing the circle at the sound hole first as it will give you an idea as to how much space you have left to play with.

  • After drawing the second circle I began cutting.

  • I suggest weighing the guitar down with something heavy to prevent vibrations while cutting the holes with a jigsaw. Start carefully and if there is too much vibration add more weight.

  • After cutting out the first speaker hole I used the cordless drill to make a small hole in the centre of the second circle to be able to cut out the second speaker hole.

One, I thought I was the only guy to think of making an acoustic guitar body into a speaker cab, and I still think it's a great idea - glad you followed through and built it. Second, upon further thought, I think it may be better to use the back of the guitar as the speaker's front, letting the soundhole be a "tuned" passive rear firing port, and an easy path out for your speaker wires. Soundholes (at least theoretically) are basically where the most sound of the widest frequency range is let out of the body. This would make very usable complementary reflected sounds if the speakers are placed somewhat close to the wall behind them. The blank guitar back (which would now be the side facing the listener) also would let you place the actual driver anywhere on it for best size fit and best resonance/freq resonance of the speaker you choose - which may be lower, higher, or off center of where the soundhole is. Sorry I don't know offhand where the sweet spot for a driver would be on the irregularly shaped guitar body as opposed to a conventional speaker box.

This looks very nice. I have been trying to do this with my guitar but i am trying to get it wired for an iPod. Would you have any ideas for me. I really don't know if the iPod would be strong enough to power the speakers. The speakers are close to 3 1/2 inches.
