I used the below project box from Radio Shack ($4, cool) to mount the kit. I keep it in the glove box for so I can unplug it if desired. I connected to the empeg via an RCA wire connected to the AUX input with the other end being a head phone male plug. I have a female headphone jack on the box (got it from Mouser, like $1) so I can unplug the AUX from the VOX box if I wish. So if I want I can then plug in an iPod or something directly to AUX and not go through the VOX. I know I didn't explain this very well but hopefully you can picture this. I'm heading out of town on vacation to the woods for 3 weeks or I'd get you some pictures now. Maybe when I get back if you are interested
