Make sure you install in-line fuse holder from the terminal of battery. GROUND To +12V DC CAR STEREO HEAD UNIT to REMOTE Turn-on from HEAD UNIT Caution This amplifier is not supplied with internal fuse in itself. Make sure you install in-line fuse holder from the + terminal of battery. Recommend 250 Ampere fuse.(saz-2500d) Recommend 350 Ampere fuse.(saz-3500d) +12V Power Connect the +12V terminal of the amplifier to the + terminal of the battery using a large gauge power wire (preferably 1/0 gauge). It is critical to utilize an in-line fuse within 8 inches of the battery to ensure safe operation of the amplifier. Make sure that the fuse is not installed while you are connecting the + wire to the battery terminal to avoid sparking and possible injury or damage. GROUND Disconnect the battery and connect the GND (ground) terminal to the cars chassis. Keep this cable as short as possible (not longer than 10 inches). Be certain that the chassis ground point is free of rust, paint, and grime to ensure a solid electrical connection. REMOTE Connect the REM terminal to either the remote output lead from the radio or another switched 12V supply such as the power antenna wire. Caution First make the ground connection, then +12V wire connection and finally the remote connection. Furthermore, the +12V wire must always be fused at the battery for protection against possible damage. If you need to replace the power fuse, replace it with a fuse of the same value. It may result in a serious hazard to use a fuse of a different type or rating. -8- BATTERY

When using dual amplifier to operate subwoofer, the positive terminal of the subwoofer's voice coil must 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. Be advised that the dual amplifier configuration has tremendous output potential, so ensure that your subwoofers can handle such a large amount of power. Caution When utilizing the dual amplifier configuration it is important to note that the connected speaker load can be no lower than 2. Connecting a lower impedance load can damage the amplifier and void your warranty -10-
Trouble Shooting This power amplifier has protection features to prevent any damages from misuse or faulty conditions. If the unit senses excessive heat, short circuited speakers or overload, the protection indicators will light, and the system will be turned off. In order to check the occurred problem, you should turn all levels down and all power off and carefully check the installation for wiring mistakes or short. If the amplifier shuts down due to excessive heat, the protection indicators will not light : simply allow time for the unit to cool. Before removing your amplifier, refer to the list below and follow the suggested procedures. Always test the speakers and their wires first. AMPLIFIER IS NOT ED UP Check that there is battery power on the +12V terminal. Check that remote terminal has at least 13.8V DC remote connection. Check a good ground connection. Check all fuses. Check the protection LED is not lit. PROTECTION LED ILLUMINATES WHEN AMPLIFIER IS ED UP Check shorts on speaker wires. Remove speaker wires and reset the amplifier. If the protection LED still comes on, then the amplifier is faulty. FUSE BLOWING Check that the minimum speaker impedance is correct. Check short on power cable and vehicle chassis. OVERHEATING Check that the minimum speaker impedance is correct. Check speaker shorts. Check that there is a good airflow around the amplifier. SOUND TOO LOW-DISTORTED SOUND Check that the input level control is set to match the output level of the unit. Check the head unit volume. Check speaker shorts. Check that crossover frequencies have been properly set. HIGH HISS-ENGINE NOISE IN SPEAKERS Check a good ground and for speaker shorts. Disconnect all RCA inputs from the amplifier. If hiss/noise disappears, check it with a good RCA interconnect. Then check the component driving the amplifier. -11-
