PIONEER DEH-3950MP

[_S7V7N_]

Bro use the " Custom " setting and try to see if you can tweak it before going and adding. Pioneer has a decent array of settings. If you want to adjust your highs then google your frequencies first and understand what the numbers that you're reading on your adjustments do, rather than trying to tune it by ear then apply that to your setting on your Headunit. There's more than likely going to be crossover settings. I took the time to Google this and wow,what an equalizer you have already :

Press AUDIO repeatedly to switch between
the following audio functions:
FAD (balance adjustment)—EQ (equalizer
curve adjustment)—LOUD (loudness)—
SUB.W (subwoofer on/off setting)—80: 0 (subwoofer
setting)—HPF (high pass filter)—BASS
(bass boost)—FIE (front image enhancer)—
SLA (source level adjustment)
# When the subwoofer controller setting is
P/O :FUL, you cannot switch to SUB.W. (Refer to
page 22.)
# You can select the 80: 0 only when subwoofer
output is turned on in SUB.W.
# When the F.I.E. function is on, you cannot select
HPF.
# When the rear output setting is R-SP :S/W,
you cannot select FIE.
# When selecting the FM tuner as the source,
you cannot switch to SLA.
# To return to the display of each source, press
BAND.
# If you do not operate the audio function within
about 30 seconds, the display is automatically returned
to the source display.
Using balance adjustment
You can change the fader/balance setting so
that it can provide you an ideal listening environment
in all occupied seats.

BAL will be displayed.
2 Press a or b to adjust front/rear speaker
balance.
FAD:F15 to FAD:R15 is displayed as the
front/rear speaker balance moves from front to
rear.
# FAD: 0 is the proper setting when only two
speakers are used.

you cannot adjust front/rear speaker balance.
Refer to Setting the rear output and subwoofer
