Hey guys, I have the AVIC-F90BT, I just installed it and I mounted the antenna on my trunk lid, but it seems like that I've been losing signal everytime I turn the music up along with my subwoofer that I have in the trunk. What do you guys think the problem is? I have yet to check the connection on the back of the unit, but when I connected all the wires I made sure they clicked in so I don't think that is the problem. Do you suppose that the bass from the subs is causing the antenna to move around and that, that is the problem?
