I know there have been other threads in the past regarding stereo issues but here goes.

I have a 2000 es300 (pioneer stereo)
I have the Scosche dash kit
I have the metra wiring kit ( retain factory amp )
I have a pioneer single din stereo with 3 set of 4v pre outs

I have everything wired up, dash taken apart all that NO SWEAT!

No issue here is I am getting zilch zero nada sound wise from the stereo, the aftermarket stereo is on and seems fine, just NO sound whatsoever to the speakers. When I turn the stereo up all the way I don't hear a single thing, no hum or buzz or anything. It seems as if the factory amp is not turning on.

Any ideas or places to start would be greatly appreciated!
