Why u want to do this? If u want proper setup, u got to use crossover for your mids and tweets, each got to do their part, crossover is to cut off freq for their respective speakers. If u do not use crossover ur speakers will play all freq, tweeters cant please low, if too low u will fry ur tweets.

U need to know what ur value caps of ur tweeter, need to know what freq it cut off in order for u to set ur mids freq
