PRESS AND t.CORR BUTTON

YOU'LL HAVE 3 ITEMS ON DISPLAY

THE BAND BUTTON WILL ALLOW YOU TO GO B/W FRONT/REAR/LOW

THE LEFT AND RIGHT SKIP BUTTONS/VOLUME BUTTON/SOURCE ON THE HU WILL LET YOU MAKE SOME ADJUSTMENTS

GO TO FRONT & REAR CHANGE IT SO IT LOOKS SOMETHING LIKE THIS 0 / 3 / 100 OR 0/4/100

THAT SHOULD TAKE OUT SOME BASS...

TOG ET MORE BASS OUT OF YOUR SUB ->

PRESS EQ BUTTON THEN PRESS AND HOLD IT AGAIN.

THEN JUST TURN THEVOLUME KNOB UP (IT SHOULD STOP AT 6)

THERE'S MORE THINGS YOU CAN DO TOO, BUT I'M TIRED OF TYPING. , LOL
