probably your polarity is wrong... other than tht... does the sound "tititi" goes louder when you press your fuel pedel? do you hav an external power amp? if you do then check the grounding... problably you hav a bad grounding for your amp or HU if you dun hav a power amp... other than tht... and never wire your tweeter -ve to the chasis....jus in case you wired the tweeter -ve to your chasis...

do post this up at the ICE sub-forum... i am sure there are a lot of other ICE sifu tht would help you out...

cheers....

if connect parallel to woofer, should have a nonpolar electrolytic capacitor in series.

it could be the interference from spark plug cable (if u are using aftermarket ones)

haha.. yeah.. could be..
but the cable only affecting radio.
cd should not affect.
