System issues!!!

[Mikemootz]

So I have a few issues going on. I have a 2020 mustang convertible that I've installed 1 12 inch sub with a amp and lc2i.
1st. I get random bass from sub while driving.
I have my ground secured and I sanded the area down to bare metal.
2nd. When I turn the car off my lc2i turns off but my amp stays on. I'm leaning towards a bad remote wire from the lc2i to the amp but I haven't checked yet.
Also I get a thump from my sub everything I start my car.

I would look at installing a 30 amp relay. Orileys or Autozone has them for under $10 bucks usually

About the LC2i, is it getting signal from the OEM sub or rear speakers? Is the Auto Sense feature switched on, or is it getting a remote signal?

It's getting it from the rear speakers. Remote signal

What is the source of the remote power for the LC2i?

The 12 volt wire for the rear camera

AFAIK, the rear camera on ly gets power when you move into reverse or on some radios, turn it on manually.

I’d suggest getting an amp wiring kit. Run the wire from battery to a fuse. Through the firewall to a distribution block. To the LOC.
The amp kits aren’t much and you know it’s done right

That's how I have it. I swapped out my LOC and it seems to be working fine now. That LC2i I have is about 3 years old
