hey, 2 weeks ago i installed a sony CDX-GT750 headunit into my car and it has been working fine until yesterday when i started experiencing static when i had it on the AUX setting. there is static even when i have nothing plugged into the front aux port of the headunit and it appears to only occur when i have either DSO / EQ on any level. has anyone experienced this problem or happens to know how to fix it? thanks in advance for your help

Check your wiring on the back of the head unit again, sounds like a poor earth

youll get static if the input sensitivity on the aux in is set too high, could try turning it down maybe.

when installing my head unit i just attached the ground wire to the existing wire attached to my old headunit. would attaching the wire to a ground point instead maybe be a fix to my issue?

Good clean earth is always a better choice Also check your batt power lead(yellow) for a secure connection

yea i got a sony cdx-gt270 and when the head unit is in aux mode static can be heard from the sub that is installed. i have a sub and amp installed, so im thinking that it is the ground of the amp thats causing the problem, am i correct?

also when changing tracks for a cd when it is in the headunit, the sub can be heard producing static

ill try fiddling with the ground to fix it and see what happens

yea i got a sony CDX-GT270, and whenever i change the track that on the cd that is inserted, static can be heard hardout on the sub. ive checked the earth on the sub and im pretty sure its good. so does this mean i have to change the earth on the headunit? like extend the earth wire and connect to chassis? ill have a fiddle around and see what happens
