Wierd noise when i hooked up my Jupiter to my speakers

[hurricanes0688 10+ year member]

I tried a ground loop isolater that got rid of some of the whining, then someone told me I should ground the RCAs, i did that and about 75% of the whining was gone. Also there is another noise in the speaker that is constant when the car is running its not a whine but more of like a drone or a constant static. What could this be. I do have a hi outpu alt, 0 gauge wire, upgraded the wires on the alt. RCAs are away from the power and the ground so what could be causing this??

Also the little overload light flashes on the xx jupiter when i have set of 6x9s and on 2 channels and my 6.5 comps on the other channels with the gain set pretty low. Hope you guys can help

You have alot going on there, and sounds like multiple issues at once. Take it to a local shop, pay them 20 clams to look it over real quick and give you advice. Its hard to know exactly what you did, and what you have, from here.

The bad thing is i didnt have this problem until i went to an audio store, i had everything in myself and needed a box built for my xxx. So i went there they told me my wiring needed to be changed and as long as i had the wire they wouldnt charge me to much to re wire the whole thing. They did and ever since ive been geting this noise. They are outta buisness now. I knew i should of done it myself but just didnt have the time with the hours i had to work last summer so i left it with them and now it has sounded like *** ever since
