HU shuts off when car is on but not off.

im trying to figure out why its shutting off. its kenwood that i got from snoopysnooper. everything works fine when the car is off but when i turn it on, it just cuts out and makes noises in the speakers.

the car has a built race motor with a big cam and everything and idles pretty low and choppy but has a 200A alty and all electrical work done. i thought that maybe i had too many things wired up to the radio turn on wire (only like 15 amps or something of fusing on it) so i was going to route the ignition turn on wire from the head unit to a fat ignition wire under the breast plate. im also going to turn the idle up a tad to make sure its not getting voltage drop. is my thinking correct? is there anything else i should try? thanks

Ahaha i seriously dont know what to say to this its like ironic twist of things besides theres the remote wire thats connected wrong try unhooking that and directly connect it to your positive wire from the battery and see if that changes anything and also when you have it directly connected to your positive to your battery turn on the car and see if it shuts off then like i said it doesnt you have to go from there to check your ignition system cause thats really only what i can think the problem is

if it is what i said than your whole ignition system remote turn on switch is wired wrong or something in it
