The installers did the right thing, but 100 feet is a lot of distance if you go unbalanced especially in case of subs. Your sub has only balanced input, if um not wrong. Whereas your avr has no balanced output for the sub. Hence they had to use a converter to terminate rca end into balanced input of your sub.
But having said that, your sub still gets unbalanced input. The converter itself cannot transform an unbalanced signal into a balanced one. You are getting very weak signal on the sub end.
