Hey guys! I just got my B-line Black Proton saga! The car quite nice! I especially like the back of it.

But I have a problem that I wish someone can help me. The B-line comes with 4 speaker, 2 at the back and 2 at the front. My front speaker doesn't seems to be working. Do I need to switch it on or something? Its no written in the manual so I hope someone can help me

Thanks
