POWER, GROUND, REMOTE CONNECTION +12V ( POWER CONNECTION ) Before mounting SoundQubed amplifiers, please disconnect the negative (-) wire from battery to protect any accidential damage to SoundQubed amplifiers and car audio system. Q1-750, Q , Q2-200, Q4-90 & Q4-120 are designed to use 4 gauge power cable and ground connection and equipped with fuses. Q and Q are using 0 gauge power and ground connection and not equipped with fuses Connect the power cables to power terminal labeled as +12V. You have to install the external fuses on the power cable for Q and Q Connect one end of fuse holders to the power cable and the other end of fuse holders to positive battery within 20cm of the same cable.

7 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 holders adequate for the application. GND ( GROUND CONNECTION ) Locate a secure grounding connection as close to amplifier 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 size 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. REM ( REMOTE CONNECTION ) Run a remote turn on cable from the switched + 12V source. You will be using to turn on the system components. This may be a toggle switch, a relay, or your source unit's remote trigger cables, or power antenna trigger cable Connect the remote turn on cable to the power terminal labeled as REM. INSTALLATION *. Installation In case, You install SoundQubed amplifiers by yourself, please read owner's manual and follow your installation steps very carefully. Before you start your installation, Please take all steps into consideration. or, you can have SoundQubed authorized distritutors to check installation and set your car audio systems *. Mounting preparation Disconnect the negative ( ) battery cable before mounting SoundQubed amplifiers 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 for SoundQubed amplifiers Please take some concerns into consideration with cooling efficiency and safety. *. Mounting location SoundQubed amplifiers use heavy-duty and good heat radiation heatsink design for avoiding excessive heat from SoundQubed amplifiers circuitry. But for better heat radiation performance, it is good to find the mounting location where you can install SoundQubed amplifiers vertically with the heatsink fins and better air flow around SoundQubed amplifiers. For the safety, You have to find dry and well ventilated location and make sure any cables and car equipment are not interfaced with mounting location. Be sure the mounting location and drilling of pilot cables for mounting will not present a hazard to any cables, control cables, fuel lines, Fuel tanks, hydraulic lines or other vehicle systems or components

8 DIGITAL MONOBLOCK S SPEAKER CONNECTIONS SoundQubed amplifiers are recommended to use 12 gauge or thicker speaker connecting cables. Run 12 gauge speaker connecting cables from your speakers to SoundQubed amplifiers mounting location. Keep speaker cables away from power cables and SoundQubed amplifiers 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 insulation from the end of each cable and twist the cables together tightly. Make sure there are no stray strands that might touch other cables or terminals and cause a short circuit. Crimp spade lugs over the cable ends or tin the ends with solder to provide a secure termination Connect the cable ends to SoundQubed amplifiers as speaker system diagram.

14 TROUBLE SHOOTING TIPS NO SOUND ( NO OUTPUT ) 1) Check all connections, cables' routing, short, voltage at SoundQubed amplifiers and headunit 2) Check fuses,if they are blown, pls replace with new one. 3) Check whether the speakers work well, you can test the speakers by connecting to another amplifier. PROTECTION SoundQubed amplifiers have the safest protection circuits. When the amplifier is shutdown, Protection LED ( RED light ) is turned on on endpanel. SoundQubed amplifiers will be back on, when resetting headunit by turning off and on if there is no circuit fault. 1) Overload : make sure the recommended subwoofer speaker s minimum impedance and do not use lower than recommended ( minimum ) impedance Single unit of SoundQubed amplifier recommended subwoofer speaker s impedance is 1ohm. Linked SoundQubed amplifiers recommended subwoofer speaker s impedance is 2ohm. Q2-200, Q4-90 & Q4-120 amplifier s minimum impedance is 2ohm stereo or 4ohm mono. 2) Overheat ( Thermal ) : SoundQubed amplifiers will be on some minutes later when they are shut down due to overheat. For better heat disspation, Pls make better airflow and no obstruction around SoundQubed amplifiers. 3) Speaker Short : Pls make sure the speaker wire connection and re-route speaker wires 4) DC offset : When oer 4V DC, SoundQubed amplifiers will be protected. Pls check whether SoundQubed amplifiers work after removing RCA-input. If SoundQubed amplifiers work after removing RCA-input, then pls measure DC by checking RCA-input L and R. DC is over 4V at input, Pls try by replacing headunit or source unit. 5) High & Low voltage protection : SoundQubed amplifiers have high and low voltage protection Q1-750, Q and Q have voltage protection range from 8.5 ~ 16 Volts, Q has 8.5 ~ 18 Volts So make sure the battery voltage whether they are within recommended voltage ranges NOISE PROBLEMS SOUND 1) Readjust input level and check the speaker quality at another amplifier. Pls replace poor quality speakers with good quality ones 2) Pls check ground contact between SoundQubed amplifiers and headunit. 3) Pls check Rca Jack and repalce with new one or re-route Rca Jack cable. 4) Engine noise is caused by poor grounding of amplifiers, headunit, other components, battery or alternator, so pls check all grounding connection. POOR BASS RESPONSE 1) Pls check speaker cables and reverse polarity of one channel
