I'm sure you saw my answer on team-integra...
New twist on the story w/the no speaker connections connected. There has to be a short somewhere, that's for sure. It's possible that it's related to your rca's, remote wire, power/ground wires as well. Take the amp out and have it bench tested somewhere. If it works fine, something is wrong w/your wiring. If it fails a bench test, then get it replaced. Hifonics is a good brand and will take care of you.
