hi guys, i met with a problem with DC offset and wish to seek whatever help i can get from here.
 
I have recently done diymod on my ipod, as such i require a cap to block off the DC offset. 
 
The dc out from ipod is 1.5V.
 
my connection is as follows
 
 
 
L out from Ipod > | | (cap) > To amplifier L
 
 
R out from Ipod > | | (cap) > To amplifier R
 
 
G from Ipod > To amplifier G
 
 
 
with the above connection, i still detect a DC offset 200mV at the output.
 
The cap i used are Mcap MKP film cap, 2.2uF 400Vdc
 
can anyone advise me what went wrong and how do i remedy it?

Bad caps?  Should be 0VDC after cap, that's kind of the idea of a coupling capacitor.

is my connection correct?
 
i tried changing to another 0.22uF wima 100vdc, the result is the same.
 
what else could be wrong?

Output of what?  How are you measuring?

I measure between "To amplifier L" and G for left output and between "To amplifier R" and G for right output.
