High Pitch Whining Through Speakers

[Plan-FAILURE]

Hey guys,

Basically when I'm not playing beats I will get a low volume, high pitch whine through my speakers and the pitch will change dependent on engine rpm.

Higher rpm = higher pitch

Lower rpm = lower pitch

Not really too bothered bout this one but would be interested to find out why it happens.

You have a ground loop. There should be plenty of information on these forums and the web in general about how to solve it now you know the term. Listed in order, the simple & typical things you'll want to check are:

* Power & RCA/speaker cabling to amplifer running down opposite sides of the car

* Adequate grounding from the amplifier to the chassis

* Adequate grounding from the headunit to the chassis

* Adequate grounding from the battery to the ciassis

There are also ground loop isolators you can add in, but they will compromise the sound quality & if your wiring is right you should never need them (In all my years of installing amplifiers, etc - I've never needed them).

Thanks heaps mate!

Did some searches and wasn't getting any results - probably due to me not knowing the terminology. My battery is not currently clamped down so I might start there and get it clamped down first as this may be compromising the battery to chassis earth.

Sounds like you headunit uses the ground from the durry lighter

i had the exact same prob after my audio install, you need to have the RCA and ground running on separate sides.
