INSTALLATION In case you install the G7 amplifiers by yourself, please read owner's manual very carefully. Before you start your installation, please take all steps into consideration, or you can have a DB Drive or DB Research's authorized dealer check the installation and help set your car audio systems. 3-1. MOUNTING PREPARATION Disconnect the negative ( ) battery cable before mounting your G7 amplifier or making any connections. Check the battery and alternator ground ( ) connections. Make sure they are properly connected and Free of corrosion before selecting a mounting location. Please also take into consideration cooling efficiency and safety. 3-2. MOUNTING PREPARATION COLLECTIVE HEAT MANAGEMENT The G7 amplifier uses a specially designed heat radiation heatsink to avoid excessive heat from G7 circuitry. But for better heat disipitation, it is recommended to find the mounting location where you can install G7 where the heatsink fins have better air flow. For safety, you have to find a dry well ventilated location. Before mounting, be sure the location and drilling of pilot cables will not present a hazard to any cables, control cables, fuel lines, fuel tanks, hydraulic lines or other vehicle systems or components. 3-3. +12V, GND, REM CONNECTION A) 12V ( POWER CONNECTION ) Before mounting G7 amplifiers, disconnect the negative ( ) wire from battery to protect any accidental damage to the amplifier and the audio system. G7 150.4, G7 250.4, G7 500.4, & G7 1250.1 are designed to use, at a minimum, 4 gauge power and ground cables G7 2500.1, G7 3500.1, G7 5000.1 are designed to use, at a minimum, 0 gauge cables. Connect the power cables to power terminal labeled as + 12V. G7 amplifiers are not equipped with fuses so you need to install external fuses. MODEL G7 1250.1 G7 2500.1 G7 3500.1 G7 5000.1 G7 150.4 G7 250.4 G7 500.4 FUSE 150A 200A 300A 500A 80A 150A 200A RECOMMENDED EXTERNAL FUSE VALUES In order to install external fuses, connect one end of the fuse holder to the power cable and the other end of fuse holder within 18in of the positive battery terminal, using the same cable gauge. This fuse location will protect the system and the vehicle against the possibility of a short circuit in the power cable. Be sure to use fuses and fuse holder adequate for the current draw application. B) GND ( GROUND CONNECTION ) Locate a secure grounding connection as close to G7 amplifiers as possible. Make sure the location is clean and provides a direct electrical connection to the frame of the vehicle. Connect one end of a short piece of the same gauge cable as the power cable to the grounding point. Run the one end of the cable to the grounding point. Run the other end of the cable to the mounting location. Connect the ground cable to the screw terminal labeled as GND. 6 C) REM ( REMOTE CONNECTION ) Run a remote turn on cable from the head units remote switched + 12V output. 3-3. G7 +12V, GROUND, REMOTE CONNECTION DIAGRAM 3-3C Remote turn on 3-3A 3-3B Ground 12V BATTERY 3-4. SPEAKER CONNECTION DB Drive recommends to use a minimum of 12 gauge speaker connecting cables. Run 12 gauge speaker connecting cables from your speakers to G7 amplifier's mounting location. Keep speaker cables away from power cables and G7 amplifier's input cables. Use grommets anywhere the cables have to pass through the holes in the metal frame or sheet metal. Connect to the speakers according to the type of the terminals on each speaker. Strip 3/8" of insulation from the end of each cable and twist the cables strands together tightly. Make sure there are no stray strands that might touch other cables or terminals causing a short. Crimp spade lugs over the cable ends or tin the ends with solder to provide a secure termination. Connect the cable ends to G7 amplifiers as shown on speaker system diagrams. 7 3-4A.

TROUBLE SHOOTING NO SOUND ( NO OUTPUT ) 1) Please check all connections, cables' routing, short and voltage at G7 amplifiers and headunit. 2) Please check external fuses. If any are blown, replace with new one. 3) Please check whether speakers work well. You can test speakers by connecting to another amplifier. PROTECTION 1) Please check overload, overheat ( thermal ), short, voltage and DC offset. 2) Minimum working impedance for 4 channel amplifiers is 2 ohm stereo or 4 ohm mono Minimum working impedance for all Class D mono amplifiers is 1 ohm for single unit and 2 ohm for linked operation. 3) If G7 amplifier shuts down due to overheat, Reset by turning off the remote input and alowing time to cool down. Please make sure there are no airflow obstructions around G7 amplifiers to prevent thermal protection. 4) G7 1250.1, G7 2500.1, G7 3500.1, and G7 5000.1 have voltage operation of 8.5V~16V If Voltage is out of range of above, G7 amplifiers will be protected. POOR BASS RESPONSE 1) Please check speaker polarities . WHINING NOISE 1) Engine noise is caused by poor grounding of G7 amplifiers, headunit, other components, battery or alternator, so please check all grounding connections. 12 LIMITED WARRANTY DB DriveTM warrants any G7TM amplifiers purchased in the USA from an authorized G7TM dealer.
