Hello everyone,

Ok so I just upgraded my stereo system and am having some serious alternator whine. This is the first time I have installed an audio system and never really new of it till now. Wondering if anyone can help me fix my problem. Sounds great when the boat is off but you can’t even listen to it when the boat is running. All you hear is the whine so it is bad.

Here is what I am running:
Rokford Fosgate 12” Marine Sub (M212S4) New
2 Rockford Fosgate 8” Marine Midrange speakers (M282) New
Kenwood Headunit (KMR-440U) New
Kicker Amp (ZXM700.5) New
Rockfor Fosgate 1 Farad Capacitor (I am not 100% sure this is working correctly) New
Boss 530 Tower Speakers with light rail (old)

Pretty much everything except the tower speakers are new so I would hope that the problem isn’t any of the components. Spent some good money on all the equipment and I was really upset yesterday when got in the boat for the first time and couldn’t listen to the stereo. Don’t know if it would help or not but I could sketch down the wiring diagram and maybe someone could look at it and tell me if there is something that sticks out there. Again this is the first time I have ever wired a system up but don’t think I am a complete idiot. Seemed pretty straight forward when I did it. I guess I must not have something grounded out right or maybe something is not hooked up correctly.

Any help would be greatly appreciated.

Thanks,
Chris
