First of all, I appreciate everyone that left input! Alandamp, I'm not trying to invent my own connections...the somewhat cheap Subwoofer that comes with the 640W has only two wires coming out the back, no plugin and no access to the inside wires. I simply used an RCA plug I had laying around and spliced the bare wires to see if it would work. No harm done, no warranties voided...just a way to try to make the subwoofer work. Didn't have another subwoofer lying around to try.
Yes, I should educate myself...I'm stuck in the old days when we used to daisychain everything. Oh, I have the manual alright...I've read it till I'm blue in the face. I guess if you don't get it, you don't get it!?
This saga all started when we bought a Panasonic SC-HT640W DVD home theater sound system. We also bought a new Polaroid 32" FLM323B HD tv. They sat for a few months while we got our house done. Found out that the SC-HT640W was just a DVD player with speakers, no connections on the back at all! Soooo, I decided to purchase the XR57 amp that I thought would cure the 640W shortfall. I spent many hours studying the manual and spent two solid days trying to get things to work. Funny...I'm usually pretty good at hooking things up electrical! Not this time! Got the TV part working fine but for some reason, I couldn't get the DVD to produce video or sound...and needless to say, I tried other connections that were not as prescribed in the manual. Nothing seemed to work to get the DVD working. Oh, it worked fine by itself! Finally, after spending so much time and listening to the wife repeat over and over, "It was working ok when you had the 640W hooked up to the system", I packed the XR57 back in the box and plan on sending the unit back. I know, it's giving up but I just got fed up. Hope no one else had as much trouble as I had this Christmas season!
