There are only two connectors to the head unit plust the antenna. The antenna just pulls out of the back of the unit. Give it some power, it won't break. I'm not sure about the premium sound and the connectors, there could be more because of the amp. Call Crutchfield and ask them about it. They are pretty good when it comes to that stuff.
