I just recently installed the f700 and i was having issues with the bass for the speakers being too much. I have a JL audio w6 hooked up to it. Usually on other decks i have had in there i can turn down the bass on the car speakers all the way so its just the bass from the sub. Every time i turn the volume up more bass from my speakers. This deck though seems as if i cant turn them down all the way. any ideas? i have had other pioneers to where i could turn the bass down all the way.
