| Hi, when I turn my sub on/off from the deck I hear a loud popping sound coming from the sub. In addition to this, if I go from CD mode to radio mode I also hear this thumping sound. The same sound takes place when I change radio stations. Please help!!! |

I am assuming the subwoofer is on it's own amp?
It usually has to do with amps.
Is there a remote wire to turn it on, or does it use speaker level signal to turn it on? |

pape:
Yes the sub does have its own amp and there is a remote wire to turn it on. |

If you disconnect the RCA's to the sub amp do you still get the pop when turning the radio Off/On.
If you have another amp (for front speakers), try disconnecting that and see if the pop goes away.
Although the fact that it does it when switching to radio and changing stations leads me to believe it is the HeadUnit. |

Check all grounds in system, including the impedence of the head-unit ground.
If all is ok, It sounds like the muting transistors on the heads output are bad.
Good luck.

| Thanks for all the help; I will look into replacing the head unit to see if that resolves the issue!! |

| I`ve had the same problem, in my case it was the ground from the amp that wasn`t connected good enough, after real though sanding the paint of the car and reconnecting the ground the problem was gone, ever since i`ve had 5 different cars and never had the problem again |

| it can be a common problem with certain brands of amps! just the design of the amp |

| its your remote turn on....is it connectde to the radios remote wire or to the acc wire? |
|

| tuneman you are thinking of a ground loop. You are close thou. if its not the ground it is in the signal from the head unit. or between the head unit and the amp.Oh by the way look at the ground from the motor ton the body this is what will cause the most confusion. |
