I am very lost here so any help is appreciated. I have a early model Technics SAGX 490. The current set up is speakers to sub, sub to rec'vr. Problem is with the volume cranked full blast I can still hardly hear anything. Sub sounds nice but something tells me this all could sound better. the speaker wires go into the high level (in an out) an the one right next to it- leaving the woofer to go into the last two on the end, Putting the rec'vr on surround sound gives the best sound the other option is 3 stereo? So steps would be just awesome!! I tried to figure out which rec'vr I have (LTR etc) I have no idea what those are and found nothing by doing a search on the forum.
