Speaker pop when vehicle is off

[Jeverall]

I just finished upgrading my base 6 speaker audio system. I replaced the 6 speakers with Focal ACX series , and did the standard kicker key 200.4 , along paired to a kicker key 500.1 and a downfiring sub in the back. It sounds great !! However I noticed that when the vehicle is off I hear an occasional pop from the speakers.

I was reading online this is a common/non serious issue for vehicles with radios that are enabled to be turned on, even while vehicle is off and key fob is not present. (I didn’t realize this was capable, but is on my bronco) .

I do have the 200.1 and 500.1 running independent power lines.

The 200.1 power and ground are running through the drivers side grommet in the firewall. I put the ground up on the side part where the hood closes. (seen in 2nd pic)

The 500.1 power runs through the same grommet, on the the same terminal, and is grounded under one of the hooks in the cargo area. (3rd pic).

Should I be concerned &/or Is there something with setup that could be causing the issue ?
could it be cause the power and ground are running close together ?

I have the 200.4 at the bottom of the steering column, with the wiring harnesses jammed in above it... The 500.1 is in the cubby area under the cargo space


Thank you in advance for any input. I am a complete novice when it comes to this stuff and couldn’t have done this without the help of this forum …. And an awesome custom harness from Hoel Wiring that enabled me to do this without needing to splice or modify any wires, fuses etc…

Using the Kicker 200.4 I had to switch from using DC Offset to 12v turn on in order to eliminate the popping heard through the speakers after vehicle shut down.

Thank you for the reply. When I turn off the DC Offset, my sub stops working?? Fwiw , here is my 500 laying in the cubby . I don’t have a “mount” for it , but seems pretty secure here. The multicolor wire from the top is runs under the cargo area, down the driverside channel(s) and plugs into the kicker key 200.4 harness in the dash. The 12V Red power wire runs the same path all the way to the battery, and the black is the ground to the cargo bolt. Then the bottom right wires are my speaker wires that are just wrapped around to my kicker sub.

On the 200.4 depress the radio detect button

It looks like it is already depressed ? (It is not pressed in )… the speaker actually made the popping noise as I was trying to get my key200 out. Below are my settings. I only have the first dip switch down , the rest all up. I just called kicker and they suggested to move my ground from under the hood to the kickpanel.

The long ground wire you are running for the 200.4 may well be the issue. I usually ground the amp as close to the amp as possible. You could also look at the quality of the grounding point. Not sure if you scraped the paint away to give a good connection, but the layers of paint might not give a great sounding point.

No experience with the Kicker amps, but in all of my systems I never use the signal-sensing option to turn on the amps specifically to avoid any possible carryover electrical noise.

Good Luck!

The area up there by the hood is painted , and I did not do any sanding or anything. I just took my kick panel off,.... again. ... and grounded to this same screw where there already appears to be a factory ground... I still have a pop

Gotta push that radio detect button in. Problem solved. You need something small to get it pushed in.
Judging by your picture it is not pushed in so it’s still off.

I thought the guidance was to make sure it was “depressed” (not pressed in)….

Ok I also just removed the cargo area again…. Going to sand the paint down around where I am placing the ground. Then I’ll make sure the radio detect is in on the 200, and see how it goes

Does this ground location look satisfactory? It isn't a flat connection for the end of my ground wire, could that be causing the issue? .

I’ve taken this dash apart like 10 times today

Well, I sanded that spot down in the cargo area, reconnected the ground, removed my 200 and pressed in the radio detect button..... and I think it may have fixed it!!!!! The only way to find out for sure is to reinstall all of the panels THANK YOU!!!
