I have a Dayton Titanic MKIII sub hooked up to a basic 2 channel receiver, which does not have a sub out. I have been using the spekaer level inputs on the sub to the mains. Is there another way to hook these up? I have been hearing that speaker level inputs with high pass filters dont sound as good, so I am looking for a different setup. I also tried hooking the sub's speaker level input to the "B" speaker terminals on the receiver with the mains hooked directly to the "A" terminals. However, it didn't seem to work well at all, I had to turn the main volume knob way up and the mains didn't sound good. I can't get a new receiver right now, so can you give me some tips?
