I don't know a lot about spyders but GM made some of their cars, like the Cavalier, run their injector relay wire through the CD player so if you removed the player you couldn't operate the car. So you had to do some crazy shit to put a radio in them.

I don't think that Spyders are this way at all, if you hear the motor clicking then it is getting power and signal, may just not be working anymore. Do you have the little clips that you have to unhook to get the top to come down? Did you forget to unhook them? If they aren't manual and are automatic then maybe you accidentally cut a wire going to them.

Not sure on that, you've got me stumped :shrug
