m not sure about the connections on the amp . would you please tell me if I am correct about these.....To Subwoofer,A&B,(output to sub cabinet,also dbx,2X6 soundfield sealed cabinet.) ,To Speakers,A&B(does this allow you to connect a extra set of speakers to the poweramp???),From Amplifer,A&B,(is this the input coming from my reciever,this is a 2 wire input,my reciever has a rca jack,is there a adptr. to go from rca to 2 wire? or can I just strip a rca cord on one end to connect these.
Hope you can help you seem to know about this amp and I can not find any info on this piece except that there are a couple more of them for sale on E-Bay right now, you might want to check them out pricing is reasonable.
