System 1
Add Power to Main Speakers
Add a GTS100 to the main
(usually front) outputs of
an existing head unit.
Secondary speakers
(usually rear-fill) connect
to the head unit's internal
amplification.
Next Step:
Add a second GTS100 to
amplify the other set of
speakers or a subwoofer
(see System 2).
System 2A
Add a Subwoofer (Active)
Use the GTS100 to drive 1 or 2
subwoofers with the head unit
powering the main speakers.
This is an excellent way to
upgrade a good stock system.
Next Step:
Add power to Front Full-Range
Speakers (see system 3).
System 2B
Add a Subwoofer (Passive)
Use the GTS100 in
Simultaneous Stereo +
Mono mode to drive main
speakers with subwoofers.
A passive crossover is
needed for this as described
on page 18.
Next Step:
Add a second GTS100 to
power subwoofers and
main speakers individually
(see system 3).
