ABOUT THE GMAA
The GMAA allows you to add a 2-channel aftermarket amplifier to GM vehicles with Class 2 data bus.
What makes the GMAA unique is that it takes the fixed level audio signal from the factory head unit before
it gets to the BOSE® amplifier and gives you a variable output. The GMAA outputs are digitally controlled by
the head unit’s volume knob. You get full range audio signal, not a specific equalized output, high passed or
low passed output.
KEY FEATURES
1. Great for adding subwoofer amplifiers
2. 2-Channel RCA outputs with left and right level adjustment for matching aftermarket
amplifier/speakers audio signal to factory speakers
3. User can select whether the GMAA will fade out when radio is faded forward/back or can be
selected to be non-fading.
4. +12V 300ma remote turn on output
5. Plug & Play, no hard wiring required

How to test for PREMIUM BOSE:
Turn factory radio volume up and down rapidly. If the sound system volume reacts immediately then the
system is NOT PREMIUM BOSE. If the sound system volume does not react immediately but instead has a
noticeable delay, the sound system is a PREMIUM BOSE and compatible with the GMAA.
Note: The GMAA is for PREMIUM BOSE Systems. Standard BOSE or BOSE use our VENDETTA II, SVEN4
or SVEN2.

2. INSTALLATION
1. BLACK 18ga. Wire - Power supply ground. Connect this wire to the same ground point where the
aftermarket amplifier power supply ground is grounded. (Fig.1). Extend wire if necessary. This wire
must be grounded before plugging in RCA cables. Failure to do so may result in aftermarket
amplifier and/or interface to become damaged.
GREEN 22ga. Wire - ground the green wire to chassis ground if you want the GMAA outputs to
fade out when you fade to the front on the radio.
BLUE 22ga. Wire - ground the Blue wire to chassis ground if you want the GMAA outputs to fade
out when you fade to the rear on the radio. If you want non fading outputs, insulate both the BLUE
and GREEN 22ga. Wire separately.
2. Remove factory 24-pin connector from head unit. Insert the GMAA male plug into the radio. Plug
factory 24-pin connector into the GMAA female connector as shown in Fig. 1 below.
3. Plug RCA cables from aftermarket amplifier into GMAA. Be sure that the GMAA black wire is
grounded first.
4. Connect the BLU/WHT wire from GMAA to remove input of aftermarket amplifier. Maximum
current output on the BLU/WHT wire is 300ma.
5. Follow amplifier instructions for connecting speaker wire and power to aftermarket amplifier
