If they didn't then no multi-driver speaker in the world would work.
'Bass blockers' are simply capacitors put inline on the + side of the speaker lead. They provide a 6 dB/octave slope starting at the frequency you select - an octave lower than the crossover frequency will deliver a factor of 4 less power to the drivers, 2 octaves you will be down a factor of 16. The door units really aren't that bad but most music today is mixed so bass-heavy they get overwhelmed. I would pick a cap that starts filtering at 80 Hz (you can find what farad cap here:
http://ccs.exl.info/calc_cr.html - from that page an 80 Hz high pass for a 2 ohm load is ~990 uF. Go to partexpress.com for caps). That will leave you punch for the bass without overdriving the units with the really low stuff.
Even if you have a sub I would not disconnect the door speakers, a 10" sub is not going to be able to accurately produce high enough frequencies to reach up to the crossover point of the 4" dash speakers. They are crossed over very high for 4" drivers.
