I have been owning Kenwood A/V receiver KR-V8050 for some time now. It's 1992 model and is working normally till now as i had been pairing that with Technics SB-G900 speakers of made year 1984. I had just bought a active subwoofer as those speakers couldn't produce bass as required due to my room being big. I have added JBL Stage A120P. All the older speakers are working great still but the subwoofer hasn't been producing any sound although it's receiving signal and all correctly. I want help with making sure i could reset the receiver or if the subwoofer then even great to make sure it produces sound.
