Engine whine with new amp

[drtjmpr909 10+ year member]

Hey guys,

I recently upgraded my component amp from a Crossfire 354 to a Kicker ZX350.4. When I first put the Crossfire in, I got a little bit of whine. Being that I am running a Pioneer deck, I grounded the RCA's and it worked like a charm.

When I got the Kicker, I grounded it to the same spot, and I am getting a ton of whine. I relocated the amp and grounded in to the same ground as my sub amp, and it is just as bad.

Could this be something in the amp, or is my ground just not good? I have the deck grounded to the frame, and my RCA's are run on opposite sides of the car.

Please Help!

Your title says Engine Whine so is this sound coming from your Engine or the Amp??
