seanb Posted January 27 Share Posted January 27 I have now been trying to find this noise for about a year and I can't seem to find a solid answer. When I am sitting in idle or will any other time really I can hear my fan click on through my stereo I also get a loud thunking noise from my RCA jacks when I unplug them or plug them in. I've been told a ground loop I've I've got three amps all of which are individually grounded to something on the car the chassis I just did all that and the noise is still there I don't know what else to do somebody says get a filter while I want to know what the problem is though there's a reason it's clicking like when I hear the fan kick on I can hear it tick.. sometimes I'll hear my turn signal like just click on it won't I don't hear it continuously but that's sometimes can anybody please help me it's driving me insane.

Welcome to the Forum. Have you narrowed it down to a particular piece of equipment? What is the Brand/model? Link to comment Share on other sites More sharing options...
seanb Posted January 27 Author Share Posted January 27 No I don't know I think it could be the crossover I have a crossover but I'm really not sure I've heard it I've heard it more with the crossover but I kind of hurt it without the crossover too the crossover is an old school like pioneer 635 I do believe I'd have to pull it out and get the number exactly I'm just not sure I don't I used to hear the whining noise like the alternator noise but I'm not sure I really hear that now now I just hear the fan kick on and off through my speakers.

Yes alternator noise is more an older school problem with older cars. The fix for that was usually a filter, or/and sometimes spark plugs made for elimination of noise. Auto Zone or whoever may be a source. Sounds as if something changed for alternator noise to go away. Also, a source of problem with let's say newer audio car systems, is the source of power to the radio and crossover. Once, it was generally powered by positive straight from the positive 12 volt battery. On some newer vehicles, there is a place under the hood main fuses box, or the inside fuse box. The ground to chassis wherever located has better chance of working when ground is free from paint or undercoating. Questions now are, is this a DIY install, or a shop? And of course, is this something you can troubleshoot yourself over the forum and, not in person...In any case, something I very seldom..think about. Maybe others here more adept can help you sort. Thanks! Oh, and was a capacitor installed? Edited January 28 by billybob 1 Link to comment Share on other sites More sharing options...

Just recalled your fan inside clicking? If so, yes some noise unwanted in your power source likely, so sure you have double checked your source. The alternator may be whining some under the load. If so, and depending on the draw, may need bigger capacity battery and or capacitor. Anyway, sounds like you will find the fix. Welcome! Link to comment Share on other sites More sharing options...
