A little bit of an update. I was able to get a hold of the AV company who did the speaker install. There is no Klipsch amp. We were supposed to be given the amp when we closed on our house, but since we were not the ones to originally design the home (original family walked away from the home before it was completed),the AV company didn't know to deliver the amp to us as our name wasn't in their books. They said they would get it to me ASAP so hopefully I'll get it soon and hopefully there won't be any issues getting it to work.
Now I just need to find out what is wrong with the DT sub. Still need to do some testing on it.
Thanks everyone for the help so far!! It is much appreciated!!!
