Help: Amp turning on and off

So i just put in some boston acoustic rally series comps and i tested them before i put my door panels back on and they sounded good and no issues. I went to go mess around with the gain on my amp and was letting them play and all of a sudden the amp starts turning off and back on in like 5 second intervals. I unplugged the rca cables and the amp stays on fine, i plug in the rear rca rables its fine, i plug in the front left its fine, front right, starts cutting in and out, then i was like screw it i need to leave, so i just left out the front right, then about 3 hours later the amp starts turning off and on again and i havent had time to test the front left cable. Before this the amp worked just fine and never had a single issue. Its an arc audio kar 400.4. And the sub amp would still play and not have any issues so im doubting its a power issue. RCA cables are almost brand new knukonceptz krystal series. I used to have memphis power reference comps in the front, in the rear i still have memphis power reference 6x9's. Help me please.

I would switch the sub rcas and see what happens. Also does it only cut out when you have it loud, or while at low volumes.

ill try that when i get home and see, it cuts out at any volume.

wow im stupid, some cables got disconnected, its all good now, please delete this thread admins
