Hey everyone, I'm getting a used 2007 SS tomorrow. I noticed that under the rear seat there was a bracket that had what seemed to be speaker wires coming out from the floor. I think there was a bose amp that is not there. Can someone please tell me what type of amp I need. (if that is whats missing) When the radio comes on it says bose. When I pick it up tomorrow, ill have a better look. :undecided
