Help installing an Alpine KTA-450 to factory radio

[OWSportninja]

So I attempted this install the other day... I bought the FOR 11CK harness for the radio so I didnt have to cut or splice into the stock wires. Wired everything up per the instruction Alpine sends with the amp. Since we don't have pre outs on factory radios I cut the RCA cable ends off (again as instructed by Alpine if you want to get speaker level signal instead of RCA) and I made sure the switches on the side of the amp were set up for what I was running. I did not run a remote wire since this amp has the auto sense technology. I ran the power wire straight to the battery with a 20amp inline fuse as instructed and for the ground I used an existing ground on the dash close to the glove box where I was mounting the amp.

SO I get all this done and go to test the sound and it sounds amazing and is VERY LOUD lol. Anywas I set all my gains and truned the bass, midrange and treble settings all the way down in the radio.

Now here's the part where my issue starts. I turn off the truck and get ready to start putting everything back together and I get a speaker pop when the truck does it shut off thing. And then another pop a few minutes later. Basically it was popping everytime I turned the truck off and not neccessarily when I turned it on although i think it did pop once when i turned it on. Is there some setting I need to turn off via Forscan in the BCM?? I just went ahead and unhooked everything because i was afraid of damaging my speakers with the pop.

Sorry for the long post but does anyone have a solution for this?

Yeah I went and order the ELM327 from Amazon and got Forscan and everything set up on my laptop. Going to attempt the install again this evening and hopefully get rid of the popping issues. Will update if successful!

I got all sorts of errors when I tried to switch my xl stereo to line out through forscan.. I've just been living with the pops ?‍

If the amp has a 12v trigger wire.. use it. That was the only way I was able to stop the popping. Tapped into the power window fuse on drivers side. Also disable the Ford EQ using forscan for much better sound - ACM 727-01-02 00xx .
