How do I get rid of the static/hissing noise thats coming from my subwoofer through the receiver? I currently have a Onkyo 7.1 HTIB that I purchased a year and a half ago. I have to keep the gains down very low and the subwoofer level on the receiver on the highest to get it at a decent level without too much noise.
If anyone has any ideas please let me know. I was thinking its just the inferior quality of the receiver that I have and planned on replacing it eventually.
BTW I am not using the subwoofer that came with the system, I am using the Dayton 500W amp and a single 12" Dayton Titanic MKIII.
Why not just ground the receiver? Most receivers have a place to hook up a chassis ground. Seems like a waste to go through all that other trouble before trying that. See the pic of the lower end onkyo below.
I was looking for that on the back of my onkyo and didnt see anything like that. I do want to note I have my dvd player hooked into the receiver too. I may try to take that out and see if that improves anything.
