CONTROLS & CONNECTIONS
SPEAKER CONNECTION
This terminal connects amplifiers to the speakers . Minimum speaker cable should be 12 gauge or larger. Connect the subwoofer speakers by checking the impedance 1 ohm for single unit or 2 ohm for strappable connection.
LINK CONNECTION
INPUT CONNECTION ;
Step 1. Connect the master amplifier to the head-unit and set its output
master / input slave switch to output master.
Step 2. Set slave amplifier output master / input slave switch to slave input.
Step 3. Connect RCA cable from the master to slave amplifier as shown in the
diagram.
POWER & SPEAKER CONNECTION ;
Step 1. Connect speaker cable ( + ) on master amp to subwoofer ( + )
Step 2. Connect speaker cable ( + ) on slave amp to subwoofer ( )
Step 3. Connect speaker cable ( ) on master amp to speaker cable ( ) on slave
amp

TROUBLE SHOOTING
NO SOUND ( NO OUTPUT )
- Please check all connections, cables’ rounting, short & voltage
- Please check the fuses , If they are blown, please replace with new one.
- Please check whether speakers work well, you can test speakers by connecting to another amplifier
PROTECTION
-
Please check overload, overheat ( thermal ), short and voltage, DC offset.
-
Minimum working impedance is 1 ohm for all amplifiers as single unit. and 2 ohm stable for strapped operation.
-
If amplifiers are shut down due to heat, they will be on some minutes later after cooling down. Please make better airflow and no obstruction around amplifiers for thermal protection
-
APK-2500 working voltage is 8.5V ~ 16V.
APK-3500, APK-4500 AND APK-5000’s working voltage is 8.5V ~ 18V -
When over 4V DC comes into amplifiers, then, they will be DC protected.
Check whether amplifiers work after removing RCA-Input.
If amplifiers work, then check DC by checking RCA-input .
When DC is over 4V at input, try by replacing +12V source unit .
DISTORTION & NOISE
- Readjust input level and check the speaker quality at another amplifier
- Replace poor quality speakers with good quality ones
- Check amplifiers and headunit’s ground contact. all grounds should be common.
- Check Rca Jack, then repalce with new one or reroute Rca Jack.
- Engine noise is caused by poor grounding of amplifiers, headunit, other components, battery or alternator, so please check all grounding connection.
POOR BASS RESPONSE
- Please check speaker cables and reverse polarity.
