The GT series amplifier you have chosen includes many unique features to enhance its performance and utility. The power amplifier circuitry is a fully discrete design notable for low distortion and unusually clean and clear reproduction quality. Your GT series amplifier will easily connect to virtually any car audio system, whether it is factory installed or purchased separately. [. . . ] Bridged Mode Operation ­ To select bridge mode operation, set the input mode switch in either the "R" only or "L+R" position. In the "R" position, signal from the right channel input is fed to both amplifier channels. In the "L+R" position, the signal from both channels is summed internally. When using a single GTS100 for mono mode fed with a stereo signal it is best to use the "L+R" mode. When using a GTS100 for each channel, or when feeding a single GTS100 with a mono signal from an 16 Speaker Level Input Color Codes Left (+): Left (-): Right (+): Right (-): White White with Black Stripe Gray Gray with Black Stripe Dual Source Remote Wiring diagram. From Head Unit #1 Remote or Antenna Output 1N4001 Diode To GTS100 Remote From Head Unit #2 Remote or Antenna Output 1N4001 Diode Using Both the Speaker Level Input and Line Level Input Together In some systems it may be desirable to use both the speaker level inputs and line level inputs simultaneously. For instance, if you have a stock head unit in your car you may connect the speakerlevel inputs of the head unit to the GTS100. You may simultaneously connect a CD player equipped with preamp volume control to the preamp-level inputs of the GTS100. The Universal Interface circuitry of the GTS100 will isolate the inputs from each other while mixing both signals. Therefore switching from one source to the other is as simple as turning the unused source off, and turning the desired source on. No other switches or relay boxes are needed. When using this setup it is also possible, using the wiring setup shown below, to allow either of the two sources to remotely turn on the amplifier. This is not necessary if the factory radio is of the high power BTL type and is connected to the speaker level inputs. The Common Sense turn-on circuit will activate the GTS100 when a powered source is used, and the conventional remote connection of the preamp-level source will activate the amp when it is used. Speaker Connections When connecting speaker wires, be sure that no uninsulated wire remains exposed and no loose strands of wire touch either an adjoining wire, terminal or a metal surface. Securely crimp or solder all connections and insulate them with heatshrink tubing. Use high quality 18 gauge or larger speaker wire for the amplifier to speaker connections. Larger wire or special high performance speaker cables may improve the performance of some systems. Be very careful when speaker wire is routed through a door hinge area to door mounted speakers. Use grommets and strain reliefs wherever necessary to prevent damage to the wires. The proper speaker connection depends on whether the GTS100 is used bridged or stereo. The speakers are connected to the amplifier with the included wire harness. If you wish to purchase the raw connector to make a custom-length harness, the part number is listed in the Specifications section. [. . . ] · Head unit not on; turn the head unit on. · Ground wire is disconnected or defective; check for continuity with an ohmmeter between the GTS100's ground terminal and a known chassis ground point. · Battery wire is disconnected or defective; check for approximately +12 volts between the GTS100's Battery and Ground terminals. · Blown fuse; check the GTS100's 20 amp fuse located on the endpanel near the power connector.
