on its way to the speakers, otherwise just go direct to the back of the speakers, and the speakers might have heat sinks on the back, and would definitly nead a source of power (like wall power).
or you could have meant: the tweeters or the amp? take the tweeters out and hook them up to another source or hook another tweeter (or whole speaker, actually) up to the amp output.
with 370 some posts you probably meant the latter, come to think of it.
this was also covered in another post and somebody had a pretty good way to check. i think 'tweeter' was one word in the title of the post.
or you could take it to someplace that installs car audio and say you will give 10 bucks for a quick check out.
