it sounds like 240zracer and gregm are saying the same thing, which finally occured to me at lunch today...at least they seem to be saying the same thing (tweeter + goes to cap and other end of cap to + binding post, then negative tweet wire straight to negative binding post).
one tweeter wire is black and the other is black and white, while the main driver wires are black and red. should the black be the negative in both cases?
anyway, thanks again guys.
oh yeah, the manufacturer told me that the cap was 0.68uf so i will take him at his word (fortunately these were rather inexpensive, though i don't won't to make a truly boneheaded error and blow something i don't need to!).
