Engine Noise

Today I hooked up my Phoenix Gold RSD comps. They played fine with the truck off, but when I cranked my truck I started getting engine noise from the tweeters. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif I tried changing the ground location for the amp and switching RCA cables. None of this helped. Does anyone have any other suggestions as to what may be causing the engine noise.

Thanks guys. I'll let you know if that works. I'm going to do it after I help my friend put a system in his Jeep.
