the reason you and others get "turn on thump" is due to the ford amplifiers using a 5volt turn on. to fix this you will need to install a 1k 1/4 watt resistor inline on the remote turn on. the resistor will act as a voltage limiter and drop the 12volt remote turnon close to ,if not exactly, 5volts (depending on tolerance percentage). once installed the "turn on thump" will be eliminated.
