i have the regular stereo on my cobalt- would like to add a set of tweeters in the doors- that looks easier than in the front pillar. how do i wire them up?

 

You need a crossover. Easiest way to add the separate tweeters is to pick up a component set which includes the 6.5 and the tweeter. As for location, it comes down to your listening preference. Don't just throw them where you think they will look good, move them around and see where you think the specific tweeters you have in your hands sound.

 

word... i started a whole entire thread on this

 

Yup, its been covered many times.
