GTR AMPLIFIERS
For 3-channel operation connect the stereo speakers to the Front terminals as described above. Connect the single speaker’s + lead to the Rear L+ terminal,
and the - lead to the Rear R- terminal.
For
2-channel (bridged) operation
connect one speaker’s + lead to the Front L+ terminal, and the - lead to the Front R- terminal. Connect the other
speaker’s + lead to the Rear L+ terminal, and the - lead to the Rear R- terminal.
• The
GTR-7535
features Front L+, L-, R+, and R- terminals; Rear L+, L-, R+, and R- terminals; and Sub + and - terminals.
◆
For 5-channel operation connect the front left speaker to the Front L+ and L- terminals, and the front right speaker to the Front R+ and R- terminals.
Connect the rear left speaker to the Rear L+ and L- terminals, and the rear right speaker to the Rear R+ and R- terminals. Connect the subwoofer’s
positive (+) lead to the + terminal, and the negative (-) lead to the - terminal.
• The
GTR-601
and
GTR-1001
feature two positive (+) and two negative (-) terminals.
◆
To power two subwoofers, connect one sub’s positive (+) and negative (-) leads to the positive and negative terminals on the left, and the other sub’s
positive and negative leads to the positive and negative terminals on the right. The terminals are internally paralleled.
◆
If you are connecting only one sub, you can use either set of positive and negative terminals.
•
NOTE:
Minimum speaker impedance for stereo full-range and subwoofer operation is 2ohms. Minimum speaker impedance for bridged operation is
4ohms.
2. Fuses:
Replace only with fuses of the same amperage.
• For the
GTR-102, GTR-104, and GTR-7535
use
30 Amp
• For the
GTR-601, GTR-1001
use
35 Amp
3. Power Input Connectors:
•
Power:
Run power wire from the +12V input to the positive terminal of the vehicle’s battery. Install an appropriate fuse holder and fuse (60A minimum)
within 18" (457mm) of the battery. Make sure the wire is not damaged or pinched during installation. Install protective grommets when routing wires
through the bulkhead or other sheet metal. Use larger-gauge wiring for longer runs.
◆
GTR-102, GTR-104
minimum wire size: 10 gauge
◆
GTR-601, GTR-1001, GTR-7535
minimum wire size: 8 gauge
•
Ground:
Run a wire (the same gauge as the power wire) from the GND input to a factory bolt in the vehicle’s chassis (see illustration below).
NOTE:
Remove any paint from the chassis for best contact. Use a star washer below the ring connector for a secure connection.
