who could help me with my setup. I recently have a thread regarding sub integration along my audio loop. I believed Amey01, Risabet & Tube60 joined in to share their insights and experiences on how to go about the topic. Unfortunately, it didn't go well with my system. Right now upon turning on my system, loud "thumping" sounds, really loud comes out of the sub and the woofers of my ML. I don't know why it's doing that. In addition to that are humming sound on the ML's (ground loop?). I'm just hoping that I didn't damage anything on my setup. I live close to WCovina.
