Is A PAssive crossover needed?

[bones justice]

i bought a pair of beyma 6.5" midrange speakers as well as a pair of beyma silk dome tweeters. I wanna put them as front speakers. can i use them as they are, or would a passive crossover be best. both speakers are 4 ohms and handle 100 watts rms.

If you run them 1 speaker per channel and your Amp has a crossover you can run them independent. Or with an Active crossover in you HU. Otherwise you will need something to limit the lows.
