Car stereo interference?

I have a mitsi lancer and i just recently had the alarm and immobiliser un-installed.Since then my stereo has been picking up noise and i cant find the source. i have an amp and a couple of subs in the boot but after isolating them the noise still comes through the car speakers. it is not loud but you can notice it when the volume is low or if a cd is paused. i checked all the wireing and nothing seems to have been changed so i think the sound is deffiently comming from the head unit. so far i have an idea it has something to do with the ignition as when you turn the key on (without starting the car) the noise starts. if i listen closely i can hear a faint pulse coming from the subs and when i turn the key off the subs pop faintly as if there is a spike going into the amp.could this have sometning to do with the immobiliser being removed?it looks as if there may have been a relay put in,is this possible? the noise is deffiently comming thru the head unit. any suggestions? thanks!
Car stereo interference?
sounds to me like you have computer generated noise.





take the car back to your installer and have him install a noise filter.
