Thanks for all the input guys. I was going to go ahead and put the empeg in there, order something to connect the audio up then be done with it. After the past oh 2 hours or so I've come to the conculsion that my wife will not be able to get the empeg in her car.

First obstacle, head unit needs to be scred in by a side adapter no problem I say lets just drill 2 small holes for the screws to slide into and connect to the empeg sled to the metal cage in the geo. Problem solved.

2nd. Go out to the car to see how everything is going to fit before drilling holes. Then notice the sled is a litter wider then the plastic in her cars allows. Try to fit it in there a few difference ways but the plastic won't allow it. I think well if it was my car no problem trim the plastic in the car down a little bit and problem solved. But like I said my wife really loves her car and won't go for it. She said she would love to have the empeg in her car but doesn't wanna do anything to car just to make it fit. Loves her car more then an empeg I guess.

Now my whole day is kinda wasted although I know have an extra empeg backup that'll just be sitting in the house 24/7 playing all my wifes music in the bedroom. Ahh well can't have everything I guess.
