i hooked up my amplifiers for my sound output to my speakers and i have no sound coming out i even tried the sub output and nothing any ideas?

did u use to have sound through the speaker wires? or is this a used unit?

i had the speakers hooked up originalyand they worked fine, then i disconnected them so i could run the rcas to the amps and from the amps to the speakers and nothing comes out.. even the sub out there is nothing..

are the amps turning on

Make sure your blue/white amp turn on wire is hooked up.
