Why does it seem that when its cold out, theres less of a connection. My right speaker sometime goes out time to time and to get it back on i turn the volume up and up until the speaker comes back on. I read when its cold the wires get smaller so not a good connection to terminal and when its hot the wire expands? Is this the trouble? I have opened up the center console before and retightening the bose amp connection thing where all the speaker wires are connected to.
