[QUOTE="Jeffdachef, post: 8285289, member: 650438"] bass boost off on both amps and head unit. Subwoofer level up to the max, EQ flat. Head unit volume at 75-90% (if you mids and highs are distorting, lower the gain on your 4 channel amp or lower the EQ on every other frequency except bass frequencies on head unit EQ. turn lpf to the highest it can go, subsonic filter to lowest it can go, Play a -6 db 50hz test tone. Turn your gain dial up slowly till you reach desired voltage. If your voltage is still low, then most likely your head unit is not putting true preamp voltage, it'll be too low. [/QUOTE]
