Alternator Whine Through Speakers

[itshimdazza]

Guys ,

I just replaced my alpine speakers in the rear after hearing crackles when pumped up finding the cone had a split in it but since doing that i am now getting an alternator noise which is pissing me off.

Does the atlernator have a condensor on it anymore or are they internal?

Would putting a filter accross the amp (in boot) or headunit work and which one?

I have put my cd on and it still comes through and even not starting the car i can even hear a slightly softened whire which i thought was my amp fan but it may not be..

any ideas would be greatly appreciated

Are your RCA's run near any power wires?

[itshimdazza]

i dont believe so..

but why would it only start when i just replace the rears as the cones had cracks. nothing else was done to it?

I'm not to sure about that. But I know I get a small noise through my speakers when I turn lights on etc, its nothing worth worrying about cause you can only notice it when theres nothing playing out of the speakers. Maybe its just something to do with the speakers, From memory the LH rear speaker sits pretty close the the battery terminals (depending on speaker) so maybe your new speakers sit a bit closer then the old ones and this is causing it? Not sure what new speakers you have but if they are the exact same speakers then that would be a bit more confusing.

Car not started and it whines isnt alternator !!

the wires are touching something or pinched

A cooling fan on amp

Can be amp, or radio and you didnt hear it before

Rca's creating inductive noise whine , power cables too close to rca's

rare but speaker wires to close to hi current or switching relay in boot

Bad cap on tweeters can do it but not common

For the other persons problem

A little whine can mean alternator ripple going up

= alternator is dying / battery or wiring issues

If you have a friend with spare speakers lying around, chuck them in for a day to see if it still does it. It might just be a crap set of speakers. Every manufacturer can have faulty gear from time to time. Most modern electronic gear will either fail in the first 2 weeks, or go for more than 2 years no problems. I hope this helps.

Hmmm no that wouldnt fix it in most cases

Hi There,

Often engine noise can be a few different things a few things to check are:

1. RCA- Use good quality shield type and keep away from the amp power cable and also the vehicles main power looms.

2. Amplifier- Gain on amplifier too high. Often people put the gain too high and this will cause excessive engine noise.

3. Cheap Amplifier- Try using a good quality amplifier or a digital amplifer often will work better then the cheaper ones.

Check these things out.

If all else fails you can use an inline RCA noise filter but these aren't the correct way to fix it and often don't always work. If you do want to try them they are about $15 generally and will plug inline with the RCA's simple fitment.

Hope this helps.
