GPA700.2 / GPA1100.2 / GPA1800.2 2 CHANNEL AMPLIFIER APPLICATIONS
FULL RANGE STEREO
This is the most basic application for the GROUND POUNDER Series 2 channel
amplifiers.
1. Interconnect cable checklist:
Connect the
LINE INPUTS
to the Radio/CD with good quality RCAcables.
2. Crossover Switch:
The
X-OVER
switch must be in the
FULL
The
MODE
switch must be in the
STEREO

FULL RANGE MONO
This application illustrates the basic mono bridging method for all Crunch 2 channel
amplifiers.
Interconnect cable checklist:
A MONO signal source is required, such as would be available from the mono sub bass
output of an active crossover, whether stand alone, or built into a head unit or equalizer.
Important:
Do not be tempted to connect the hot, or positive outputs, from any source
together to obtain a mono signal, as this could very well damage the output stage of that
source.
It is necessary to feed the SAME signal to both left and right inputs via a Y-adapter RCA
cable. Connect the mono speaker positive terminal to the LEFT +, and its negative
terminal to RIGHT -.

3. Crossover frequency control checklist:
N/Afor full range operation.
4. Line Level:
Refer to the section
"Setting up systems after installation for best performance".
NOTE: Minimum final loudspeaker impedances:
4 &-2-Ohms stereo mode or 4-Ohms mono mode
Switch setting checklist:
- The
X-OVER
switch must be in the
FULL
- The

Crossover frequency control setting checklist:
N/Afor full range operation.
TIP:
If you are using the mono sub bass output of an active crossover, there is nothing
wrong with switching in the low pass filter in these amplifiers for a steeper low pass roll-off.
Minimum final loudspeaker impedance:
- 4-Ohms mono.
Use both connectors for 4 CH amplifiers
