so i have this premier 500UB running a rockford fosgate prime 300.4 and a pair of DD components. im using the DD crossover, the tweeter is at 0db.
i set the headunit to custom, yet when i scroll btwn low, mid and high, non of the available settings (can adjust hz and btwn 1n 2n 1w 2w) make any type of audible difference in any speakers. i can still fade them in and out and adjust source levels. my subs are on a different amp and theres no audible difference with them either, which lead me to believe it isnt a problem with the crossovers or my front stage amp. anything i could look into other than buying a new headunit? anybody ever have a problem like this? possible solutions?
** also, i use an ipod for my music but ive also tried changing settings using a cd and theres no change
