Ok so I have my iPod and XM hooked up to my N3.... and no matter what source I'm using whenever the music hits a specific picth, note, cord, tone, ect the music cuts out on me--- So any type of song with alot of treble in it is hell.. Now YES i've tried lowering all the settings and such and even had my installer take a look at the problem....tested the speakers with a diffrent head unit---and even tried another N3 unit and the N3 is the only unit to give me this problem....his only idea was to amp my rear speakers-----has anyone had any trouble like this? or have any ideas? if none of thi
