Odd Knocking Noises after Audio Upgrades

[Erik638]

I made Several Audio upgrades and now I got some odd noises happening.

So a quick run down of my evolution of audio upgrades. My issue has to do with the last two things I did I believe but just in case this is what I have done.

1. Upgraded rear speakers with SSV works pods with kicker speakers.
2. Upgraded front speakers with kicker CS Speakers.
3. Added a kicker key 200.4 amp plug and play under my steering wheel.
4. ForScan tweaking.
5. I have a 23 model that had the fake sub and amp. I purchased a kicker 6.75 sub and a used ford fusion amp. Swapped out the dummy stuff for this.
6. Forscan turned on Amp/Sub

So my issues started after steps 5/6. I gradually started hearing odd noises coming from the back of the bronco. Almost like a slight knocking. It has gradually gotten worse. Now it is happening when the car is off. It happens a good amount when opening doors when the car is off. Does not really happen or I don't notice when playing the radio.

I guess a few questions. What could be causing this? Bad amp maybe? A bad wire? Me screwing something up? Any ideas how to fix? Next question is can it be running my battery down when the car is off? I got the odd message on my FordPass app saying it was not going to monitor the car b/c I was having a battery issue. I had been traveling for work but when I got back to car it started right up. Not sure if the two things are related or just some odd fluke.

Could it be a pop from the sub from the amp turning on/off?

Some Fusion amps have issues with the 5V turn-on signal from the Bronco, they want a full 12V signal and can turn on and off randomly

Just a shot in the dark

I suppose it could be but it's happening when the car is off and it's not just once like tit is turning on or off. Multiple times. I can probably live with it until I do a real sub/amp upgrade if I knew it was not going to kill my battery. I'm paranoid. I went to Costco and bought one of the car jump things and threw in my back.

I don’t have a sub, but when I installed the Kicker Key in mine, I had like a static popping sound coming from speakers and turned out I had the radio detect push button in wrong position. Honestly can’t remember if it’s in or out. But that fixed mine.
