I need help programing my Alpine CDA 9835 EQ and Crossover to get optimal sound.

 

crossover is set to your likings. it all depends what kind of sound you want to get and what type of equipment your running. usually, if you have a sub, set the low pass at about 50-60hz. if you have dedicated midbass run them between 50-160 or so. then, for the highs, set that anything about 160 or so.

 

is a 300hz bass blocker too high for a rear deck. i have 2 12" subs in the trunk. do you think that will take away too much mid?
