I got a wierd question. Ok what is the big deal if a amp is running off of 1 rca cable or 2 because my amp i have only works when i have one plugged in but when i plug both of them in the amp sounds like it turns off and gets really quiet. ok if both r plugged it does it give it more power rather then just having one plugged in? I also did try changing the rcas already and it still does the same thing, and also if both rcas r plugged in does it make the system sound better and louder or will it sound the same even if only 1 rca is plugged in
