Hello, I have a Sony Analog Home system with 2 Fulance Tower Speakers 12” woofer, onkyo center, Subwoofer and I’ve dealt with home theater system before but I change my system to a new receiver (HT-R510) and no sound was coming through and I had no problem switching back to my Sony so I did, and when I did that I must’ve hit something but when I did it totally switch my audio and it used to be near perfect, and when now when I use it sounds muffled and like it’s only coming though the center speaker I did change the gauge on one tower speaker from a large gauge to a smaller cable, connections are all good and clean, it just doesn’t sound near as good as it did, I need some settings help
