How do I get rid of static in the car radio....can't listen to it when the engine is running?

Question

we tried resistor spark plugs but they doesn't seem to help...hope someone can..........

Answer 1

There are a couple of reasons for the static, signal degradation due to Rf interference usually because of an unshielded antenna cable or a wire next to the antenna that is putting out EM (electro-magnetic) interference. If the static is apparent on all functions i.e. CD, and radio. The it is something between the amp and the speakers that is causing the problem. Check to make sure the screw mounts are firmly in place and you get no vibration in the system, then check to make sure there are no power wires on top of or next to the casing as these can create Rf and cause your system to feed back slightly making a static to ground. Check also to see that the speaker wires are firmly in place and have no breaks in the line or are not next to power or high frequency lines. I don't know how old the radio is, or what the hook-up is, but it sounds like you either have a faulty install, or the system is not shielded properly. Suggest you check the items mentioned, you may also want to change out the fuse, it may have a phase short that's causing it to cross link within the fuse panel. You may also try changing the position of the ground wire the radio is using as this can create problems as well. Hope this helps.

This is due to electro static caused by your engine running. Can cure this by getting a thing called a noise filter that goes inline with the power supply with your radio's wiring. Or your car is in desperate need for new spark plug wires.

Answer 4

Did you change the Spark plug wires? try a different brand some times they affect the radio. Also I don't know if you have an after market radio or not but if you do try changing your grounding point its weird you will get ground loop hum of certain stuff.

Enjoying the feeling of motherhood and raising a family would surely be a couple’s dream. Some get it naturally, while for some others things don’t seem to work as they desire. These reasons which stop a women from conceiving can be due to either physical reasons or truly physiological.

Answer 7

All you need is a noise filter (inductive type) that's wired between the radio and fuse block (battery).

Answer 8

Car Radio Suppressor

Answer 9

* The type of noise suppressor you need depends on what is causing the noise in your system. Obviously, the trick is to determine what the source of the noise is. The information below may be helpful in finding the culprit.

* Read over this article for some hints and explanations of what can cause noise in your system. Then use this diagnostic flowchart as a guide to walk you through the troubleshooting process.http://www.crutchfieldadvisor.com/ISEO-rgbtcspd/learningcenter/car/noise_diagnose.html



Dealing with noise
Noise can be introduced into your system from a number of sources. This is especially true if you have an amplifier. The type of noise you're hearing can help determine the cause.

If you have an external amplifier in your system, the first thing to do is to quiet any system noise, which sounds like a constant, low hiss. First, check for system noise with the engine off. Insert a blank tape or put your CD or MiniDisc player on pause. Listen to the system with the volume completely down, then completely up. Put on music. If you hear hiss in either instance, adjust the gain on your amplifier.

Pass more signal from the receiver to the amp by leaving the receiver's volume higher before you set the amp's gain. Experiment until you eliminate the hiss or reduce it as much as possible. A tiny bit of hiss is OK — you won't hear it while driving.

Engine noise
If your problem is related to engine noise, you may hear a whining or clicking sound. Its pitch will vary with engine speed. Most noise problems come from a poor ground. Always make sure your ground wire is connected firmly to bare metal in the event of a noise problem.

You can also try isolating your amp from the chassis of your vehicle by mounting it on a board or using rubber grommets or feet; using a different brand of patch cables; or, only if all else fails, installing a noise suppressor. The tricky part is figuring out which step or steps to take. Please read the rest of this section and try some of the simple tests.

Noise in the patch cables
Noise can be picked up by the RCA patch cables connecting your components. To test this, detach the cables from your amp. Insert one side (left or right) of a spare patch cable into the amp's left and right input jacks (see illustration below). Turn on your system and engine.


If the noise is gone, reconnect the cables to the amp, and disconnect them from your receiver. If you hear the noise, your patch cables are definitely picking it up. Try re-routing them. Separate them from your power cable by at least 18 inches. You could try a better brand of patch cables. The inexpensive RCA cables many people use to connect their components don't have the insulation or conductivity necessary to deflect noise in a metallic, highly conductive automobile.

How much noise your cable receives depends largely on the size of its loop area (the distance between its center conductor and outer shield times the cable's length). Consider trading your old cable for one with a twisted pair design. You'll get a smaller loop area and less noise.

Noise picked up by antenna/power cable
If it's not in the patch cables, the noise may be coming in through your antenna. Plug all your patch cables back in and unplug your antenna. If the noise goes away, try an antenna noise suppressor. This filter plugs in-line between your receiver and your antenna, breaking the ground path between them. If you still have noise after unplugging the antenna, it may be coming in through the amp's main power cable. Try thicker cable.

Radiated noise
If it's not the antenna, try pulling the receiver from the dash while a tape or CD is playing. If the noise goes away, it's being radiated into your system. Try using magnetic shielding foil (also called Mu-metal) to shield the back of the receiver or wrap the wire or component (such as a digital clock) that's radiating the noise into your system.

Noise in speaker wiring
Noise can also come in through the speaker wires. To test them, turn the system off and disconnect the speaker wires from the amps. Now start the car. If the noise is still there, then it's being radiated into the speaker wires. Reposition them, or, as a last resort, shield them by wrapping them with Mu-metal foil.

Noise from electrical system
If you've tried all of the noise-fighting tips above and you still hear the noise, the problem might be with your vehicle. You might simply need to fill your battery with fluid. If that doesn't help, have a mechanic check your alternator and battery.

If your car is older and hasn't been tuned up recently, you may have ignition noise. It's a ticking noise that varies in speed as you accelerate. You may need a tune-up involving resistor-type spark plugs, shielded carbon-core spark plug wires, distributor cap, and coil.

If the noise doesn't disappear, then your ignition system may not be grounded well enough and is broadcasting ticks to other items such as your air cleaner, hood, exhaust system, etc. Chances are, grounding one of the under-hood components will eliminate the noise.

This site http://etronics.resultspage.com/electronics/Noise%20Suppressor has a few of them listed..As you can see they are pretty cheap..I sure you kind find some just about anywhere like circuitcity or bestbuy..

Good Luck and i hope this helps.

You may need to change the car's antenna.
