Ill have to look at the manual again but visually there where four patch cables out the back, 2 red 2 black i think, should be for F/R L/R, and the book said a preamp output.. is this the same as a sub out? or ina 5 channel amp can the pre amp out of my head unit be used to provide the Sub input on the amp?

Thanks though for the info before and any other help you may give .:thumbup:
