haha its definitely not CAT 5
It's for sure Romex. Not Cat 5, 6, or 7. Sucks, and sounds retarded for someone to wire it with that, but apparently in 1993-1994 area, the electrician felt it would be a cheap and good way to use up all the excess house wiring. Each volume whole in the house has at least 2 romex ends coming through it. Then a couple sections where they routed 4. You should see the main port where all the wires combine to input in the Distributor or Reciever. Its an entire closet dedicated to a HUGE Romex monster. A crap load of romex ends, all labelled with old cracking yellow tape of which room it is wired to. Its a headache to look at, but actually quite funny. Especially listening to all the comments about how hard it is to organize and use. My thought is to buy some type of 2 channel amp to connect to the Reciever, then a distributor, hopefully able to organize the wires better and make the job a little easier. Maybe the Amp will help carry the signal across the house better. I dunno. Just an idea i was reading on some websites. The 12 channel amps that would be ideal are WAY TOO insanely expensive.
