Can someone help me out here....dunno if anyone is having the same problem or anything but i got an
iphone 4s not even a month ago, there is just one problem... hissing, crackling & popping sounds when playing.
I use a AUX cable (dont have usb port) and never had any problems with it, ipod touch used to work fine. It don't really happen with iphone 4 nothing like that.
I have tried changing setting about with the phone, the car and nothing... i can play any song and within seconds there is a hissing noise in the background which is rather loud and annoying. I love listening to music in my car and its a shame cause it makes my sound system sound crap
i have made no real changes anything, speakers are the original and added focal 6x9 and a edge sub (had it all done proper) i have never had this problem before. Can anyone help me out, maybe have an answer for me? anyone had the same problem or do you think its just the phone... even when i stop playing the music it still is hissing, popping and crackling at me.... HELP! 
thanks x
