Bump Bump Noise from Speakers

[ramrebelwonk]

Hello,

I have a brand new Rebel. Whenever I get in the truck there is a "bump bump" deep bass noise that comes from the speakers. The truck is not on or running even. It's like the truck senses I'm there and some system is activated.

Can anyone shed some light on this phenomenon?

I don't know what causes that, but as soon as you unlock or open the doors, there are systems that start activating. One of those is the infotainment system. At least it does on my 12". But, I don't get that sound. I have the Alpine system. It could be Bluetooth connecting to your phone.
