iPhone amplifier / Speaker out of Wood iPhone amplifier / Speaker out of Wood

This is a terrific project that I decided to build for myself.  I never want to spend $75 on an iPod / iPhone dock that burns through batteries, but I would like an amplifier for my iPhone.  This wooden iPhone dock is a fantastic project.  The plans were inspired by others around the web including and a similar iPhone amp project at

This project was a great one that allowed me to work with my 9 year old son.  He was happy to work with the drill press to help with the holes and with the spindle sander to clean them up.

I built mine by using 3 pieces of Cherry that were left over from a past project.  I love working with Cherry and the finish always turns out terrific.

There are 3 basic pieces.  I began with Part 2 since it had the most work and would be the least visible since it is sandwiched by parts 1 and 3.   Follow the Sketchup plan (click the image for the file download, or

To construct your own, fabricate each of the 3 pieces from the Sketchup plan.  Once you have your three pieces, align, glue, and clamp.  After mine was fully set, I flushed up the edges with my chop saw.  In addition to that, I wanted my iPhone amp to lean back a bit.  This would help to retain the iPhone and give a more professional (finished) look to the piece.  I set my saw blade at about 10 degrees and took a sliver off of the bottom.  I also decided to put a routed edge on the speaker holes.  I used a simple 45 degree chamfer bit.

Perform any finish sanding needed, apply your sealant, paint, or stain, and enjoy!
