Annoying Audio Whine
 

I'm not sure if this is an easy fix or appropriate for this section but i recently got a sub, amp, and head unit installed in my 93 GT and there is alot of audio whine. Does anyone kno why that would be or how to fix it?

RFI, radioshck or any other eletronic supply store will carry a noise filter that will make it go away!

That is a very annoying sound indeed lol! mine use to be in sync with the rpms sure yours is too! usually cones from the ignition system!

they make little devices to plug into your rca cables to help the whine.

having bad plug wires can amplify the issue due, mine did such

Before you spend any coin replacing parts or buying filters, make sure you have a DAMN GOOD ground for your amp. Putting the grounding lug onto painted bodywork with a sheet metal screw through it is not enough. Sand a clear spot through the paint, screw the ground lug down and if in doubt, add another grounding lug to another point in the body.

Just my $.02 but I've seen (heard) it happen more than once.

2 things you can check make sure the power wires +and- and remote are not running next to the rca wires if so run the rca wires on the other side on the car if fine have your alternator check out it mite be going bad

thanks for the replies guys i did end up figuring it out..there were so many wires running in the same spot and it seems it wasnt grounded enough..best buy "ground loop" 15 bucks runs right into rca's in amp..no more whine

stock alternator cant handle the amperage draw!frpp offers an alternator swap kit w a very simple connecter change over.its very customer friendly and inexpensive.trust me been there done that!!!!
