well im not planning on changing the mids or the tweeters as of right now, i simply dont have the money or the time, since im moving to a new state in 1 month. it seems imminent that im goign ot have to change the head unit so i guess for now ill just run the amp off of the rear speakers, and once i come up with another $300 ill just purchase a new head unit and work towards some decent mids and tweeters.
