either subwoofer or component speakers in a bi-amplified system, or conventional full-range speakers in simpler systems. The GTS300 and 600 also include preamp-level outputs which can provide either full-range, high-pass or low-pass signal to drive additional amplifiers.
2 before disconnecting the battery! 2. Run a minimum A WG #8 power cable complete with a 40 amp fuse (not included) for the GTS300 or an A WG #6 or A WG #4 cable with an 80 amp fuse for the GTS600 directly from the positive + 12V battery terminal to the disir ed amplifier location.
9. Fuse – 40 Amp A TC type fuse for the GTS300 and two 40 amp fuses for the GTS600. 10. Gain Control – Use this contr ol to adjust the input sensitivity of the amplifier .
3. System Design Using the GTS300 or GTS600: 3.1 Speaker Requirements When used in the non-bridged mode the GTS300 or GTS600 can easily drive 2 ohm speaker loads. When only one speaker is connected to each channel, virtually any conventional speaker may be used.
components is extremely important for proper performance and long term reliability . All wiring connections should be made either by soldering with heatshrink tubing insulation or with high quality crimp type insulated connectors installed with a good crimping tool.
5. Internal Adjustments Speaker -Level Input Impedance Adjustments The speaker level inputs of the GTS300 and GTS600 come factory set with 100K ohm input impe- dance.
Regardless of whether you build or buy it, the necessary resistor network has the following configuration: Custom “Chip” Construction • Each resistor in the package has the same value.
6. Input Gain Adjustment Before operating the GTS300 or GTS600, recheck all wiring connections to make sure they are correct and secure. Be sure that a fuse (40 amp for GTS300 and two 40 amp fuses for the GTS600, not included) is installed in the +12V line near the battery .
7. T ypical Applications The following diagrams show the most common basic system configurations of the GTS300 and GTS600. A combination of one or more of these “building blocks” may be combined to form elabo- rate system designs.

8. In Case of Difficulty Power -on light does not come on Power light is on, but no sound is heard from some or all of the speakers • Head unit not on; turn the head unit on. • Ground wire is disconnected or defective; check for continuity with an ohm-meter between the amplifier’ s ground terminal and a know chassis ground point.
Power On light is blinking, indicating a fault condition, and sound is intermittent or off Alternator whine through the audio system with the engine running Bass output from speakers too low • Defective GTS300 or GTS600; If ther e is audio signal present at the input of the amplifier and there is no output, the GTS300 or GTS600 may be defective.
