well why would y ou do that? you want the amp(s) to turn on with the radio don't you?
But, if you just wanna be different. then a simple switch is all ya need opened/closed contact with nothing on the open contact (middle) 12v on the top and the amp remote wire on the bottom. then it's just a matter of flickin the switch. np. You won't need relays or anything cuz the remote is like half an amp or something small like that. You could use a foglight switch or heated seat switch for that stealthy look other wise any switch will be fine dude
