Hello, I would like to add another power plug to run the power to my 5 volt XM radio. I have removed the amp that came with the car from under the seat, so I was wondering if I could tap into the old amp power plug to provide the power. I want to make the line hidden to look finished and don't want to use the normal plug because of the cup holder over it. Do you think that would work. I would want it to stop providing power when car and radio off. Thanks
