+12V PowerConnect the +12V terminal of the amplifier to the POSITIVE terminal of the battery using the same diameter as the ground cable, making sure you install in-line fuse holder, approximately 300 or 400 mm.From the POSITIVE terminal of battery, making sure that there is no fuse in battery holder.

GROUNDDisconnect the battery and connect the GND (ground) terminal to the car’s chassis. Keep this cable as short as possible ( not longer than 20 inches or less ).Making sure that the connection with the chassis is rust free and clear of paint or grime.

REMOTEConnect the REM terminal of the amplifier to the power antenna terminal in the car ignition switchusing 12 or 16 ga electrical wire.

CautionSAZ-1500D, SAZ-2500D & SAZ-3500D are not supplied with internal fuse in themselves.Make sure you install in-line fuse holder from Positive terminal of Battery

Using a dual amplifier configuration, the MASTER amplifier has total control over the SLAVE amplifier.When using dual amplifier to operate subwoofer, the positive terminal of the subwoofer's voice coilmust be connected to the positive terminal of the MASTER Amplifier and the negative terminal of the subwoofer's voice coil must be connected to positive terminal of the SLAVE Amplifier.When hooking two amplifiers to it, please check the power handling capabilities of your subwoofers if they are not exceeded.

SUNDOWN amplifiers have protection features to prevent any damages from misuse or faulty conditions.If SUNDOWN amplifiers sense excessive heat, short circuited speakers DC, or voltage the protection indicator will light, and the system will be turned off. In order to check the problem, you should turn all levels down and all power off and carefully check the installation for wiring mistakes or short. If SUNDOWN amplifiers shut down due to excessive heat, they will be working later when it is cooled down. Before removing your amplifier, refer to the list below and follow the suggested procedures.

Check remote turn-on voltage at amplifier and headunit, when remote turn-on voltage is low or no turn-on voltage, there is no sound.Check fuses at the battery side or external fuses and all wire connections.Check RCA Input is properly connecte

Please check POWER, GND and REMOTE wire connection and other wires properly connected.When DC over 4V come into the amplifier, amplifier is DC protected. Pls check whether amplifier work after removing RCA-Input. if amplifier work, then check DC by checking RCA-Input. When DC is over 4V at input, try by replacing head-unit or source.When amplifier is over-heated, Amplifier goes into the thermal protection. Amplifier will be back to work after cooling down little bit. Please install amplifier in better ventilation and make it cool.SAZ-1200D, SAZ-1500D, SAZ-2500D & SAZ-3500D have minimum working impedance as 1ohm as single unit. Linkable connection is 2ohm. SAX-125.4 minimum working impedance is 2ohm stereo or 4ohm mono. Make sure Chassis and Remote use same GROUND

Please readjust amplifier input level which is printed on endplate.Make sure good ground contact of amplifier or headunit.Use sufficiently shielded RCA interconnects and good RCA routing.Check all ground connections of all other audio equipments.

Check speaker wiring and reverse polarity.
