If so, what LOC specifically do i need to use to convert the singal so a normal non-balanced input amp can be used? or is this even possible? the amps i am wanting to use are an alpine PDX 4100 and PDX 1000.

When searching for this do a search for balance receivers. Line Output Converters normally take balanced speaker level outputs and convert to rca level inputs. Most are inductor based and from I have been reading the effect is typically muddy sound at best. Look for IC based balance receivers.
