Quick Question?

[EzRush 10+ year member]

I'm having some issues with Alternator whine on my setup, odd thing is when I shut the car off and the deck is on during that delay and there is no noise. I'm having a hard time tracing down where the noise could be coming from. I have the ign hooked up to the fuse panel and the deck power is going to the battery also the ground is right near the deck. Everything as far as I could tell is grounded properly no paint anywhere and nice and short.

Just can't figure out where I'm getting the noise from.

Any opinions?

Setup

I grounded the chasis of the alpine head unit and the sound did get lower but it's still there. What else could I try.

noise through the sub or through the mids/highs?

RCA's too close to power wire maybe?
