yUmadBro Posted June 25, 2012 Report Posted June 25, 2012 So i had another 4 chan hooked up before i swapped my amps. then i made a swap and immediately im getting a loud whining noise but only when the car is turned on. i tried replacing the rca wires and it made a very small difference but not to much. Someone told me to try a ground isolator, so i borrowed one and tried it and its still whining terribly loud. Any ideas on what i can try would be great. Thanks Quote

SnowDrifter Posted June 25, 2012 Report Posted June 25, 2012 The amp is making the whine sound? Or the speakers hooked up are making a loud whine? Does it increase with engine RPMS?

Kyblack76 Posted June 25, 2012 Report Posted June 25, 2012 I like this thinking here Does it increase with engine RPMS? let us know...... Quote SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold
yUmadBro Posted June 25, 2012 Author Report Posted June 25, 2012 it slightly increases when i accel, but not always. it sounds like the whines coming through the speakers but its loudest when the trunk is open so thats why i assumed the amp. it is a pioneer head unit 70.99 special. i seperated the rcas from the power when i tried a new set but it only helped the noise a very little. even when the headunit volume is at 00 the whine seems the loudest, as i turn the volume up it seems to slowly go away but still very evident Quote
SnowDrifter Posted June 25, 2012 Report Posted June 25, 2012 Try a different head unit. My buddy was having a similar issue with a Pioneer head unit. He changed it out and the problem went away Quote ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444
yUmadBro Posted June 25, 2012 Author Report Posted June 25, 2012 i have a kenwood headunit laying around somewhere i can give a try tomorrow but its weird because i didnt have this problem until i switched the amplifiers and components. i check all my speaker leads and they look fine to me. Quote
soundstream15 Posted June 26, 2012 Report Posted June 26, 2012 i had the same prob with my pioneer deck, it kept making a whining noise so i sold it. im not a fan on pioneer decks tho Quote
yUmadBro Posted June 27, 2012 Author Report Posted June 27, 2012 i switched the pioneer out to a jvc and the noise is gone. Quote
Miguels Posted June 27, 2012 Report Posted June 27, 2012 (edited) is your amp grounded properly? it might be the problem, edit: double check all your grounds and if you can upgrade the wire it will be better, alternator whine is not always a deck issue Edited June 27, 2012 by Miguels Quote my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/
