Hey guys, purchased a pioneer 4200ub with plans on redoing my entire car audio system. I wired all the rca cables and power cables for my speakers; I only installed the front speakers though and hooked them up. I have my amp connected to the power cable and it's grounded as well. I have the front rca cables hooked up to the head unit. To sum it up, I have the front speakers hooked up only to my 4 channel amp and I decided to try and see if everything works so I hooked up my head unit. However, it does not start up. Nothing starts actually. The amp doesn't even show it is powered on (the LED light is not on). I'm not sure what's going on. Will the amp not turn on if the head unit is not on (thus not sending current through the remote signal wire)?

I don't know why the hell my head unit won't turn on at all though. yellow > yellow. black is grounded. red > ignition. orange > lighting. This is really fustrating. I was planning on having it done today...

I forgot to mention, my wiring harness didn't even fit so I had to cut it up a little and it still doesn't fit. Even if the pins weren't connecting correctly, wouldn't the amp power on LED still light up?
