[QUOTE="anking33, post: 386789, member: 553006"] In response to the questions and suggestions: The amps and fans are wired as such; 1. The lead wire goes from the head unit to the rear of the car. 2. The lead splits in order to connect to the two amps and the fan relay. 3. Because the remote lead is a circuit, some of the voltage from the turn-on lead goes to each of the amps. The amps are internally wired to complete the circuit, i.e connect to ground. 4. The relay most also complete the circuit, so it is also wired to ground. 5. Thus, it doesn't matter which amp or relay is connected first(in a physical sense) because they all share the same potential(voltage) which is the voltage of the turn-on lead. I know this to be true, I tried every arrangement possible, even running the remote lead in series with the two amps. Plus, for those of you with your wheels turning, I ran a range of resistors in series with the relay, incase the relay was shorting the amps. At best the amp power light would flicker on and off and the fan would run. Everything points to the remote lead not having enough power, does anyone know a quick fix or alternate wiring config [/QUOTE]
