Should I get a noise suppresor, if so which one?
Will it help. Where do I hook it up?

I still get some noise coming thru, that annoys the fu*k out of me. Like when I step on the gas, I get a whine...

I have a RF 800.4.

I think I need to get new RCA's also, would that help.
I don't think my are double sheilded rca's. Will it make a difference?

Lettme know...
Thanks

 

before buying a suppresor, there are a few things you should do. first, where are your wires being run? cheap rca's have a better chance of allowing noise to enter the system. how close are your rca's to your power wires? best thing to do is run them down the opposite sides of the car. speaker wire should also be kept away from the power wire. also, are you using the ground in the wire harness? i've never had a problem with mine, but it is best to run a new ground from the radio to the chassis. how are your amps wired? those grounds should be as short as possible. realize, a suppresor will only make the noise quieter, it will not get rid of it totally.

 

wires are on oppiste sides of the car

Power left, rca'/speakers right.

I'm just wondering about the suppressor thing

 

sorry bro... thats a dieing alt.

its alternator whine, i have it too. im prepping for its death. get ready to invest in an alt because thats what gives power to your computer to run your car, so must have.

suppresor wont help, what that can be used for is if you have an ignition box and its picking up interference.


later bud...

 

I don'y think it's the alt, cause I just replaced it with a 180amp.

and That is the only prob I'm having.

It's driveing me nutz.

 

An alternator going bad could cause the problem, but I don't think so in this case...

Several things to try first...


1. Disconnect the RCA's from the radio side. Test the system to see if the noise still exists

2. Reconnect at the radio side and disconnect the RCA's from the amp side. Test again.

If you have multiple components in your signal chain (eq, crossover, etc...) then continue to remove single pieces from the chain until you have isolated where the last point is that the noise is still there. If it were the amps or the RCA's, then you will generally hear the noise still with the RCA disconnected from the radio...if that is true and the noise goes away when you disconnec them from the amp side, then the noise is being induced through the RCA's...if it is still there then it could be a grounding problem at the amplifiers or whichever the last portion of the chain to cause the noise is.

Now, another thing to check is to be sure that your power wire run under the hood is not immediately next to your spark wires or distributer...a bad set of wires or bad rotor can also cause the induced noise because of the ammount of loss that is occuring.

Get back to us when you have tried disconnecting each piece and let me know the results...shouldn't be too hard to find.

 

Kewl, I'll try that tonight.

I wonder why I never thought of that that...

Dumb me
