ok i swapped my OEM tweeters out for a set of alpine r series that come with my components. I used an inline crossover on them both. im getting a slight buzz/hmm from the passenger side. i know its not the crossover or tweeter cause i swapped the drivers side over just to check. same buzz on pass side. drivers side has no buzz. so im thinking its something with the car that is adding the buzz. anyone come across this? the next step would be to ditch the inline crossover for the big boxy ones that came with the alpines. but i would have to mount them under the dash and run wires. the buzz is gone when the radio is off and is present with every source( dvda,xm,cd,radio).

any suggestions?
