What could cause my crackling sound in the sub?
Hello, I have an old original vintage OptiDrive 500 driving a single JL
12w0. I am getting crackling and popping sounds coming out of my sub. The sounds seem to be constant in volume regardless of the volume of the source. Even if the volume is turned all the way down I get these noises. It is mainly in the first few minutes after turn on however it can show up at any time seems. Thanks. |

There first thing I would recommend is to go through your system and make sure there are no lose wires, particularly lose or damaged RCA's. If this noise is a recent occurrence and you had no problems before, damaged or lose wiring is the most likely culprit. However, if your wiring is fine, it may be emanating from somewhere in your car's electrical system. Perhaps an accessory or computer in your car is malfunctioning and producing some type of interference. If the alternator is malfunctioning, this can also sometimes occur. Or, of course, perhaps your amp is finally giving up the ghost. MOSFET |

Well, after replacing interconnects, head unit, ground and power wires, and
changing the location of the ground. The crackling noise is still pesent. The dealer has deuced that the amp has a problem. They are goingto apply my full purchase amunt to a different amp. One recommendation is a JL Audio 250/1. Any comments about this amp? I am driving a single 12" sub (JL Audio 12w0) and it is in a standard cab full size pickup. |

Sorry for the spelling and grammar in the previous post. I was obviously in
a hurry. |
