My amp will not work when RCA cables are in?

I received a new amp today. Its a Kenwood kac-9104d. I had a kenwood kac-x20 and the RCA cables worked fine for it. But when I hooked up my new amp it powers on just fine but when I hook up the RCA cables to it(from the head unit) the red light on the amp keeps flickering. It lights up then flickers for just a split second and it does it over. But when I take the RCA cables out the red light says on fine. My REM(remote) connectors for the wire are bent and are not on the best. Same for one pair of the speaker connectors. May this be the problem. Or what is? I know the OHMS are matched perfectly. But I am not sure what the prob is. The subs are SVC 4ohms 400W rms 1200 W RMS.
