Like the title says I had a avic d2 installed, and a few weeks later back passenger speaker pops when I hit a bump. Not to familiar with car electronics. Should I try to pull the unit out to see if there is a loose connection, or should I pull the speaker out of the door. Plays fine when it s not popping, only on the bumbs does it sound bad.

in my experience, it may be a lose wire some where, and when u hit a bump it shakes the lose connection,

check all off your connections and make sure there tight.
