12" Sub and Amp Install

[GR128]

So I installed an Alpine 12" type S sub and a 1250W Soundstream mono amp in my 5th Gen.

I've got an interesting yet troubling problem I've yet to figure out.

I have what sounds like a ground loop of some sort going on however, when I roll either the drivers window or passenger window down about half way the engine hum noise goes away.

I can eliminate the noise by opening either front door as well.

I have verified multiple times all my ground connections and made them as short as possible at the amp.

I've also tried a couple different ground loop isolators with no effect.

New cabling no change.

I guess my next move is trying a different location to pull ACC line voltage for the remote turn on to my amp.

I removed the remote turn on to the LOC to see if that would help because it can trigger ON automatically when it receives and input.

I know audio wiring issues can be a PITA but I'm open to suggestions!

Thanks

Are you using RCA cable or a high frequency converter to get the sound to the amp?

A common problem is running your amp power and RCA cables next to each other.

I usually try to run the RCA cables down one side of the vehicle and power down the other side.

Not sure what your setup is, but maybe this will help.

EDIT: I didn't read the entire post at first.

Looks like you got it figured out.

I know this thread is super old. But does anyone have any guidance on what I’ll need besides this ANC bypass cable?

The ANC bypass cable eliminates the feedback created when adding higher powered speakers into the system.

Nothing else needed to accomplish this.

I picked up an anc bypass (aph-CH03).

Tons of stuff I don’t need in the kit, but it was the 280$ that the other harness eas

What have you guys used for the sub input and remote turn on for your LOC?
