It costs extra money and the noise filter drops the voltage going to the component as well. This is a poor attempt to fix the problem and doesn't always work. Instead of fixing the cause of the problem a noise suppressor will try to cover it up in a 'band aid' approach. Noise suppressors are not a solution in my opinion. Keep in mind that sound deadeners tend to be heavy so if vehicle performance is important to you make sure you keep the weight down by using sound deadeners sparingly or by going with a lighter weight deadener sheet or spray on material. These are best left to the professionals or the adventurous DIYer. Liquid spray on deadeners are popular for the interior door panels but are a little messier to apply. Have this checked out by a qualified body repair person. Rattling trunk lids may be caused by a loose trunk latch or a worn weather seal.

If you have a rattling license plate than adding a layer of sound deadener behind the plate will definitely help. Sheets tend to work well and are relatively easy to apply. B-Quiet also specializes in sound deadening and though their line is not as varied their prices tend to be less expensive. Dynamat has the most extensive product line as this is their specialty.

Other well known manufacturers are Stinger (Road Kill), Scosche (Accumat), Rockford Fosgate (Dead Skin), Raamat, Second Skin and B-Quiet which makes a product called Brown Bread. The most well known brand of sheeting material is Dynamat, a product of Dynamic Control. The most commonly available product in the automotive aftermarket is the viscoelastic sheets and spray on materials. Various clays and putties are also used to act as an absorber between two body panels. The thick padding underneath the factory carpeting is a type of noise dampener. Noise dampeners can be any material that is used to reduced body panel noise.

Body rattle can be solved as easily as tightening the bolts and screws that hold the panels together or may require a full array of noise dampeners. Large and luxury cars are usually built with thicker metal and more sound absorption materials and are less prone to body rattle. Door noise is less common and is usually more of a problem on the less expensive cars. Less noticeable examples are interior panels that are worn and may slap together when a bump is hit.

I'm sure everyone has heard a car booming down the street with the body panels shaking and rattling with every bass note. Note that the diagram is slightly different if the accessory has a relay in the circuit. See the diagram below to see how this is done. You may need to place the capacitor on the load or the power side of the switch (maybe both). Adding a small bi-polar capacitor (0.47 uF) between the accessory's power wire and ground will often absorb these surges. These high current drawing accessories are causing a voltage spike that is traveling into your car audio equipment with the result being heard as a sharp pop. This can be switching on your turn signal, headlights, brakes, windshield wipers or even the rear window defrost. Twisted pair cables will usually be less prone to noise than their coaxial counterparts.ДЄccessory pop is associated with one particular electrical event in the vehicle. You might also consider switching your RCA cables to a twisted pair model. You'll also need to make sure your charging system is in top condition and that your connections between the battery and components are secure as well as the integrity of the factory ground strap, an often overlooked component. It is usually cured by grounding the equipment directly to bare metal on the chassis rather than an available factory ground bolt as is often used to save time. Most of the time this is caused by a poorly chosen ground for a piece of equipment. Alternator whine will be heard as a high pitched whine that will rise and fall with the engine speed.

Here's a few of the most common noises found in car stereo and how to fix or avoid them.ДЄlternator whine is the granddaddy of car stereo noise. Unlike home audio systems, car audio systems have many sources of noise to deal with. One of the most frustrating aspects of car audio is noise in the system.
