2. High Pass Filter (HPF)
This knob controls the input frequency range for amplifica on. Therefor you can cut out the bo om
Frequency with a range from 0Hz to 300Hz ahead of amplifica on for a limited Output Signal.
Note: The bo om frequency range ever effect into most stress to the amplifier and loudspeaker.
Cu ng bo om frequencies ahead amplifica on increase the energe c balance and longlife of your
Equipment while the Distora on of Sound get decreased and higher output Levels are possible.
EXCURSION SMART OEM Upgrade Concept recommend PXA 45 Amplifier with PXA B8
ac ve underseat Subwoofer for a perfect audio quality even of the bo om frequency range.
3. Subwoofer RCA PRE Output and REM Output Signal
Via the included interface the EXCURSION PXA 45 provide a PRE Low Level Signal for the PXA B8
underseat Subwoofer or EXURSION SXA or HXA MONO Amplifiers as well other Power Amplifiers.
At same me it can provide a 12V REM TURN ON/OFF Signal for proper func on of all Amplifiers.
Note: The most common way of installa on within our recommonda on will be, via the 1,8m
20 Pole ISO Harness, at the front underseat loca on of car. Therefor, for this short distance, is
only a RCA Male Adapter demanded to the EXCURSION PXA B8 underseat Subwoofer.

7. POWER CAP (acity)
Within EXCURSION SMART OEM Upgrade Concept we focus to the basic handicap of all kind of
Plug & Play installa on = limita on of the Power and Ground cable wiring. Too small diameter
of the Power Cable effect into losses of voltage at higher consump on demands. Less Voltage
effect direct into losses of Power and Sound Quality with much higher Distora on of the Signal.
Especially in challenge with all kind of music material every amplifier need stable power supply
to perform at its best fine and rough dynamic according the origin recording without distora on.
In order to perform at its best quality we recommend to hook up at all kind of Plug & Play installs
an extra Power Capacity. This local Energy Storage provide quick impulsiv discharge power supply
while con nous stable recharging of the Capacity Storage via the Plug & Play harness is possible.
The Power Capacity Storage follow in size the total consump on. Sure increase in case further
PXA B8 underseat subwoofer or Power Amplifiers get distribut connected via the CAP Terminal.
Note: Op onal Power Capaci es are recommend in short distance with 12Volt Caps & AGM Ba eries.
