Engine noise through your auxiliary input?

pie1_mediumRecently, we have had people calling in and telling us that they have engine noise when they are listening to their plug and play satellite radio inside their car. Every time they accelerate they can hear an engine noise or a “wine” through their speakers. Well, we have found a solution. Here’s the scenario:

Problem: When the listener accelerates down the road they can hear an increase in engine noise through their speakers.

Solution: We discussed this with a professional installer that used theĀ PIE in-line 12 amp noise filter and it solved their problem. What they did was go behind the cigarette lighter and put the power filter on the live wire running to the cigarette lighter. This solved the issue immediately.

One way to prove this theory to is to plug in a regular MP3 player into the auxiliary jack on the radio and drive around. Even better, if you have a stiletto you can listen to recorded content through the aux input as well. You should hear no engine wine noise at all. If you do, then this is a completely separate issue. Most engine noise issues come from the fact that the unit is drawing off of the vehicles power through the cigarette lighter, or in rare cases, from a vehicle power hardwire kit. Both scenarios can be solved by using this PIE noise filter.
