I am using JBL component speakers and I don't hear any hiss. however, the sound quality overall is bad in this system and I suspect a software issue rather than a hardware issue.Sounds really good???
So you don't hear any noise in quiet parts of a track if you play at low volume with engine off?
I guess speakers with high sensitive would make the static noise more obvious. But I find it so bad that I think it would be quite obvious with normal oem car speakers.
