Keep as short as possible (< 20" / 50 cm). Use minimum 0AWG cable for optimal operation. +12v (Power connection) Connects to the positivie terminal of the battery. For specified performance 0AWG cable is required. Fuses shall be placed within 8" / 20 cm of the battery. Connect the +12V wire, keeping in mind that this wire must be fused at the battery as well. Ensure the ground is appropriate, then connect it to the amplifier. Connect the switched remote. Reattach the negative wire (ground) to the battery. Operation over 17.5 volts will cause the amplifier to go into protect mode and can void the warranty. 5 installation Installation Considerations Installing an amplifier on your own can be a rewarding project, but it's important to approach it with caution and thorough preparation. Reading the owner's manual thoroughly will provide you with the necessary knowledge and precautions to take before beginning the installation process. If you find yourself uncertain at any point, seeking assistance from authorized distributors or dealers is a wise choice to ensure that your setup is correctly configured and your warranty remains valid. Remember, safety and proper functioning should always be your top priorities when handling electronic equipment. Preparation When installing an amplifier in a vehicle, it's crucial to disconnect the negative battery cable to prevent any electrical shorts or damage. Ensuring that the battery and alternator have secure and corrosion-free ground connections is vital for the system's performance. The amplifier should be mounted in a location that allows for proper cooling and is safe from excessive vibration; improper mounting can cause damage and hurt performance. Mounting the amplifier vertically helps dissipate heat through the heatsink fins effectively. It's also important to ensure the installation area is dry and well-ventilated. Careful routing of cables, especially the RCA cables, away from high-current wires minimizes interference and alternator whine. Keeping a good distance between RCA, power, and speaker cables can further reduce potential noise and safety hazards. Power connectors 12V (Power connection) Before mounting the amplifier, disconnect the negative (-) wire from the battery to prevent any accidental damage to the amplifier or the audio system. The amplifiers are equipped with 0 AWG power and ground terminals. It is crucial that all terminals are used with the appropriate cable to ensure correct operation. Connect the power cables to the power terminal labeled as +12V. These amplifiers are not equipped with fuses, so external fuses are required at both the battery and the amplifier. Connect one end of the fuse holder to the power cable and the other end of the fuse holder to the positive battery terminal within 8 inches (20 cm) of the same cable. The same should be done at the other end of the cable that connects to the amplifier. The fuses will protect the system and the vehicle against the possibility of a short circuit in the power cable. Make sure that the fuses and the fuse holder meet the system requirements. GND (Ground connection) Locate a secure grounding connection as close as possible to the amplifier. Ensure the location is clean and provides a direct electrical connection to the chassis of the vehicle. Connect one end of a cable of equal size to the positive cable to the ground location. It is important that the ground cable is as short as possible, but no longer than 20 inches (50 cm) at maximum. Run one end of the cable to the grounding point and the other end to the mounting location. Connect the ground cable to the terminals labeled as GND. REM ( REMOTE CONNECTION ) Run a remote turn-on cable from the switched +12V source. This may be a toggle switch, a relay, the source unit's remote output cable, or power antenna trigger cable. Connect the remote turn-on cable to the power terminal labeled as REM. The REM out terminal is mainly intended for connection of another amplifier run in a chain, but it can also be used for other units. INPUT (RCA CABLE) Run the RCA cables away from the high-current cables and speaker cables, and connect them to the amplifier. Use high-quality cables with a secure grounding point to avoid amplifier malfunction and/or alternator whine. 6 speaker connection Speaker impedance 1 Ohm ~ 8 Ohm will reach thermal at a faster rate & will eventually go into protect. Impedance load under 1 ohm is not warranted! We recommend using minumum 8 Ga speaker cables to acquire the intended performance & efficiency. Run the speaker cables from your speakers to the amplifier's mounting location. Ensure these are ran separately and away from high current cables and if possible the RCA cables as well. In all cases where cables are penetrating the vechile's chassis use grommets to protect the cable. Connect the speaker wires according to the terminals on the speaker(s). Strip 3/8'' / 1 cm of insulation of the end of each cable and twist the cable strands together tightly. Make sure there are no stray strands that could touch other cables or terminals as it can cause a short circut. Crimp spade plugs over the end of the cable or tin the ends with solder to provide a solid terminal. Connect the cable ends to the amplifier as shown in the diagram. Note, the amplifier's speaker terminals are internally bridged. CAUTION Connect the +12V wire, keeping in mind that this wire must be fused at the battery as well. Ensure the ground is appropriate, then connect it to the amplifier. Connect the switched remote. Reattach the negative wire (ground) to the battery. Operation over 17.5 volts will cause the amplifier to go into protect mode and can void the warranty. 7 daisy chain - master and daisy mode master daisy In daisy chain mode, the master amplifier's audio settings, such as gain, crossover, etc., are routed to the amplifier marked as daisy. From that daisy amplifier, you can route the input signal from the master amplifier to a second daisy by using the output RCA on the first daisy amplifier. You can continue adding amplifiers in a chain this way. This feature is very useful when you run multiple subwoofers and have a hard time gain-matching them. If there is a slight voltage discrepancy between the master and the daisy amplifier, you can use the gain daisy to fine-tune the signal by +/- 5%. 8 accu8 crossover accu8 · The accurate crossover setting Dealing with guesses and improper settings of your crossovers seems futile when you have invested both time and money into your audio system. If you use a DSP, you can set the crossovers at any specified frequency you see fit. On the amplifier's crossover setting, you would have to rely on costlier tools or guesses. The ACCU8 feature eliminates this challenge. The potentiometers, except for the gain, have a 41-click ratio when turned. Each of these clicks corresponds to a specific frequency or level increase in dB. The chart below indicates these settings.
