Anonymous | Well my rca is on the other of the amp which is about a foot and a half long and my remote is right between the power wires im mean literly right in between and close but thats how the amp is made |

The remote wire has nothing to do with the audio signal going into the amp. It simply carries a 12 volt current to the amp in order to turn it on. |

Gold Member Username: InvainMichigan United States Post Number: 3253 Registered: Aug-04 | Yes. You want to keep your RCA cables as far away from anything carrying current as possible. |

Anonymous | Well that is on the other side of the amp there is an output and an imput rca hole (RED AND WHITE) my rca wires are RED AND BLACK so i would assume i would plug the red in the red hole and the black in the white hole both in the input side Or do i plug in in the output? |

Gold Member Username: InvainMichigan United States Post Number: 3257 Registered: Aug-04 | Yes, you put the red rca into the red rca input on your amp, and the black into the white input, only if you have the rca's hooked up at your headunit correctly. Just make sure you have the left going into the left, and the right going into the right. |

Silver Member Username: Mikechec9Chicago/atlanta Post Number: 554 Registered: May-05 | "Yes. You want to keep your RCA cables as far away from anything carrying current as possible" yeah, that's a common conclusion. but it's a myth. the voltage potential is carried accross the the vehicle's chassis-the ground plane. so its going to induce the same noise as running the signal/power cables side/side. So basically, the electron potential of the car's chassis acts as an antenna for noise anyway. so unless you can prop your wires up above your car by plastic sticks, it won't make a difference how close you run your cables. |
