Setting The Bass Maximization Control

The Epicenter Plus is the most powerful bass processor in the history of 

autosound.  Able to leap tall buildings with a single bound and all that kind of 
stuff.  With that in mind we have equipped The Epicenter Plus with two different 
Bass Maximization selections.  If you should need to change the settings, please 
use the chart below for guidance.  A word of advice: listen to the factory setting 
before changing your Bass Maximization settings.

PFM Subsonic Filter

Many car audio systems truly push the limits of their subwoofer...without 

really knowing it.  Tuned enclosures affect the roll-off of many speakers, yet 
lots of source material forces the speakers to play lower than expected.  The net 
result is wasted amplifier power and damaged speakers.  The AudioControl PFM 
(Programmable Frequency Match or Pure F#@&% Magic) filter is a program-
mable subsonic filter.  It allows you to let the speaker play only as low as it 
should be playing.  Because every system is different, we allow you to change 
the PFM roll-off frequency to whatever you choose. 

On most systems, the factory installed module (33Hz) is fine.  If you know 

the tuning frequency of your speaker enclosure (porting frequency or 3dB down 
point), you might try setting your PFM module to that frequency.  If you want to 
protect your speaker system even more, you might even try a higher frequency.  
Often a higher frequency actually sounds louder and cleaner.

TROUBLESHOOTING 

No Power

Check the “Power” light  on the chassis of The Epicenter Plus.  If the “Power” 

light is on, you will want to check to make sure that the cable connecting the 
dash remote to the chassis is not pinched or disconnected.  If the “Power” light 
is off, check to make sure that the power wire and remote turn on wires are con-
nected or a fuse has not blown. 

No Bass Restoration

When your system is playing and yet you don’t hear any difference in the 

sound, try turning the knob clockwise.  If you still don’t hear any affect, then 
you need to make sure that you have The Epicenter Plus in the right part of the 
signal chain.  It must be installed BEFORE any crossovers in the system for 
best, thundering performance.
