hey i just ordered my speakers 4x6 polk 40w rms and pioneer 6x9 40w rms . Im kinda new to car 
audio and i was wondering  should i put bass blockers on the 4x6s? and if so how many hz bassblocker?
 
i also for got to mention i am not putting in any subs and im not amping the speakers.
 
you shouldnt need to

I may run 18s, but I can do your taxes in 10 seconds flat.
 
 
if you do decide to put the bass blockers on the speakers. ide do 60-80hz on the 6x9s and maybe 80-125hz on the 4x6.
Thats if you decide to do it.
