Aftermarket Radio Alternator Whine fix ??

[thedailyh2]

hello ! I have a 2004 H2, I've had 2 aftermarket radio/multimedia and both have that Alternator whine coming out from the speakers i think..goes louder when you accelerate.

Is there a universal part or a specific part / noise suppressor I can get? Searched a bit and found this PAC SNI-1 Noise Isolator , will this work?

I don't have the experience to check electricals, looking to buy a part and get an electrician to do it. Thank you !

Yes, it wires into the power wire going to your radio, which is where alternator whine usually comes from. That's where I would start first, it's cheap and easy to do. I dont know if the one i linked is quality or not, just a suggestion of the type of electrical noise filter you need.If you still got the whine then it's coming from somewhere else and you'll have to chase it down. It could also be coming from power wire going to your amp if you have one.
