I needed a power socket for my GPS so here it is. Box is made of a part of a phillips surround sound speaker. Mounted an aux. power socket on passenger side, 1/8 audio input on driver side for speaker.
Here are the side pics. The odd looking spots are hole that I filled in with silicone. I was going to use duct tape and paint it black but decided to use silicone. If you look in the mirror you can see the cup holder I bolted on the back panel.
