how to use high pass filters

If I have a tweeter that has an in line high pass filter with it can I run a different tweeter without an in line high pass filter in and have the second tweeter feel the effects of the high pass filter? Or do I need to run the high pass filter of the amp to get the effect of the high pass filter on the second tweeters? Will this have any effect on the tweeters with the high pass filter already in line receiving the same audio? Also, can I run the tweeters with the in line high pass filter in them in series? Finally if I run the in line high frequency tweeters parallel with regular component speakers will this have any effect with the amp in full frequency mode?

A passive crossover that came with a speaker/speaker setup, is designed to work with that speaker/speaker setup. If you add another speaker/speaker setup, you change the impedance seen by the crossover. This will either raise or lower the crossover point by one full octave. In the case of a tweeter, this could possibly damage the tweeter.
