yeah theres a remote turn on coming from the deck, doesn't seem to be an inline fuse, not sure how to check the amps...its the mach 460 system so i'm pretty sure theres 3 amps, one under the deck and then two near the truck..not sure how to really get to those or check the fuses on those

 

test the remote turn on to make sure it has voltage on it with the deck on.

it can't be too many more things before you need a new radio.

 

remote turn on is fine

i plugged my stock radio back in and I get the same response with that, so it is not the radio at all, my guess is that something is up with the amps but I dont know how to check on those
