Awesome thanks man!Nope. Your amp has built-in high level inputs. Use those instead of the RCA's.
Almost all modern amplifiers, including the exact one he chose, have built-in LOC's. The need for an additional outboard one is pretty rare today.Yes will need an LOC/2. I did allot of research on upgrading the suvmwoofer and Crutchfield was insistent the need for an LOC 2 to clean the aignal before going to the amp.
