Iphone 3g Line out Problems

[Chemdawg]

Well, my first post, and it's already a negative one.

So far I have owned several Ipods, including a touch. Now I own an Iphone 3g. My problem is with the line out on the iphone. I have an Ipod adapter kit for my car, that plugs into the accessory output on the Iphone (Charging plug). My music sounds HORRIBLE. I have never heard so much distortion in my life. So I start playing around with Itunes, and find that if I change the Volume under Album info/Options, and turn it down REALLY low, it sounds good in the car. HOWEVER. I also purchased a set of S9 Motorola Bluetooth Headphones which requires a bluetooth adapter, (Plugs into the same accessory port), the music is WAY TOO quiet then.

I cannot find a sweet spot with this line out. I was told I should not have to adjust anything. That this PRE-Out so to say is better than the headphone jack. NEGATIVE.

Does anyone know how to adjust the sound of my MP3's, so that I can use my accessories? I find it awefully hard to believe that I can use my Old HTC phone with the bluetooth headphones and listen to my MP3's without a hitch. Yet this HIGHTECH Iphone here sounds horrible? Something is not right.

Oh yeah, I already played around with the sound check, so that can be counted out.

sounds as if some of you accessories are not completly compatiable with the iphone. older car gear is usually always a tad iffy but i know how you feel with the supposedly super phone
