subwoofer sound upon entering.

[Jake1050]

When I get in the truck but before I start it (I think) I hear a subwoofer speaker like sound. Is that the ANC turning on or just the sub coming on or just something else? Anyone else notice this weird sound?

Mine does, too. I don’t have a sub, though. I think it’s pretty common.

I'm not sure I have one either. Still learning this truck. It's just the best way I can describe the sound.

New truck question. Speaker noise when first open door normal?

Let me know what they say about the speaker pop, believe all of them do it w the HK 19 Speaker system. Its annoying and definitely not right. I forgot to ask them about popping when i was at dealer last week. They updated the BCM and one more item, not in front of me now. As far as fuel...
