I am replacing my amplifier, as my first was stolen. There are RCA jacks running from the receiver to the hatch. The tips of the jacks have a post sticking out, with what look like clips that would fit around the perimeter of the female plug. They also appear to screw on such that it tightens those clips. When I try to connect them, however, they are totally loose. The only thing I can think of is that when the receiver was stolen, there were small rubber disks laying in the hatch - do they somehow tighten that connection? If this is the case, where would I pick up replacements?
Any help is appreciated.
