I am looking at using a Zapco 2 channel amp monoed into a single sub and using a Tru Technology 4 channel amp for the mids and highs. My concern is the symblink patchcord that the Zapco uses. Does anyone know if it has to be used with the Zapco, or if any RCA cable will work? Is mixing the 2 brands going to cause any conflicts? Or should I just stay with Zapco for the 4 ch amp as well?
