X-OVER: 

Choose which mode the amplifier should use. HP = High-pass filter mode, FULL = 

Fullrange mode (no filters are used) or LP/BP = Combined High/Low-pass filter mode.

High-Pass Filter (HPF):

 10Hz-4000Hz variable, no frequencies below the chosen frequency 

cut point are allowed to pass through to a speaker/subwoofer. 

Low-Pass Filter (LPF): 

30Hz- 4000Hz variable, no frequencies above the chosen frequency 

cut point are allowed to pass through to a speaker/subwoofer. 

The MAX A2 amplifiers are designed to offer you the option to either connect them to a 

subwoofer or to full range speakers/midrange drivers. The built-in crossovers need to be 

set correctly depending on type what type of setup you are going to apply. On the following 

page we show the most common settings to use on your amplifier.

If you want more help/guidance in how to use the filter settings, consult your local GAS CAR 

AUDIO dealer.

The crossovers are used to regulate the maximum and minimum frequencies each speaker 

is allowed to reproduce. The first thing you need to do is to find out the frequency response 

of each speaker you wish to connect to the amplifier. Don’t allow the filters to pass through 

lower- or higher frequencies than your speakers can handle. 

The different frequency bands reproduce different types of sound:

Example: A2-100.2
