New member Username: MayormaynotPost Number: 2 Registered: Jan-12 | Hi Joe, Thanks for taking the time to help me with my problem! The suppressor I am using is a Scosche In-Line Power Lead Noise Suppressor. I have the RCA cables (of the suppressor) connected directly to my head unit,and the RCA cables coming from my amp are ran along the passenger side to the front of my truck and plugged into the other end of the suppressor. I have a Ford F150 so my amp and subwoofer are under the back seat. } |

New member Username: MayormaynotPost Number: 3 Registered: Jan-12 | That is the exact suppressor I have installed. What is the difference between that and a "power lead" type you are refering to?? And yes, it took away the engine noise (humming between tracks, thumping when turning the system on/off, and the high pitched sound of the engine when I excelerated) but now my subwoofer doesn't even sound like it's on. |

Here is a an example of the power lead type: http://www.sonicelectronix.com/item_38579_P.I.E.-NF-20.html It's installed at the power leads of your head unit leaving the signal path intact. I don't know how much effort you are willing to put into this and how familiar you are with electrical systems. |

New member Username: MayormaynotPost Number: 4 Registered: Jan-12 | don't really feel comfortable messing with the electrical system. Would it just be best if I just took out the suppressor and tried to find another way to fix my engine noise problem......at least I would be able to hear the bass in my subwoofer. Are there any other suggestions you have for me to try once I take out the suppressor?? |

Gold Member Username: Joe1234Post Number: 1139 Registered: May-09 | If you have an older Pioneer HU there is a particular solution for those, if not you can try any of the following: 1) exchange your RCAs for high quality ones AND route them in different ways to the amp. 2) connect the chassis of the HU to the chassis of the car to a location that is as nearby as possible to the HU. This must be a tight solid connection. 3) install a power lead supressor like the one above to the HU. 4) check that all of your amp connections are tight and clean specially the ground to chassis one, but also the connection to the battery and the inline fuse of that connection. Now to mitigate the problem you can lower the gain of your amp as possible and use the volume on the HU higher, that reduces the amount of noise being amplified. Most issues will resolve or improve with these measures, if nothing of that helps then additional steps can be taken. |
