dErZ Posted October 30, 2012 Posted October 30, 2012 I can hear a faint hissing noise when listening to either the radio or cds. Just sounds like static. Is this normal? I have the bose headunit. Quote
Sly@Kaizer Motor Posted October 30, 2012 Posted October 30, 2012 Is it there all the time or only when the engine running ? Quote
Dblock Posted October 31, 2012 Posted October 31, 2012 Usually means a bad ground. I never has it when I had the Bose? Quote
taffyjason Posted November 23, 2012 Posted November 23, 2012 mine started hissing when i changed my HU, very quiet though, i presume a bad earth Quote
H5 Posted November 26, 2012 Posted November 26, 2012 It is called floor noise - can be improved by sorting out the earth and the power supply. However, ultimately it is normally down to the weakest link in the system, often the OEM amp and cabling. If the pitch changes when you rev the engine then it is definitely the earth. HTH. 1 Quote
