just like it says above... i installed a set of alpine components and tweeters in my caqr on monday and a set of co-ax in the rear... and i realized tonight coming home from work that the front left alpine component does work but the tweeter does and they are hooked up to the same 2 way cross over. i have each side(left and right) front and back speakers running in parallel to a 2 channel amp...any reason why the one speaker wouldnt work when the tweeter does?????? any help would be great
