POWER CONNECTION

BATT ( 12V POWER )Before mounting ampliﬁers, disconnect the negative cable from the battery to protect any accidental damage to your ampliﬁers and audio system. Connect the power cables to power terminal 12V.All DAK-series mpliﬁers are not equipped with fuses so that external fuses should be used.Connect one end of the fuse holder to the power cable going into the ampliﬁers and the other end of the fuse holder to the positive battery. 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 )Locate a secure grounding connection as close to the ampliﬁer as possible. Make sure the location is clean and provides a direct electrical connection to the frame of the vehicle. The ground needs to have as low of a resistance as possible. Connect one end of a short piece of the same size cable as the power cable to the grounding point or to one of your batteries or battery bank. Run the other end of 4 ga cable to the mounting location of the ampliﬁers for connection to the ampliﬁers ground terminals and connect the ground cable to the GND ( ground terminal ).REM ( REMOTE )Run a remote turn-on cable from the switched 12V source. This may be a toggle switch, a relay, your source unit’s remote trigger cables, or a power antenna trigger cable. Connect the remote turn-on cable to the REM ( remote ) terminal.

TROUBLESHOOTING

DAK-series ampliﬁers have protection features to prevent any damages from misuse or faulty conditions.
If DAK-series 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 DAK-series 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.

NO SOUND ( NO OUTPUT )

Please check all connections, cables’ routing, short & voltage.
Please check the fuses, If they are blown, please replace them with a new one..
Please check whether speakers work well, you can test speakers by connecting to another ampliﬁer

DISTORTION & NOISE

Readjust input level and check the speaker quality at another ampliﬁer. Replace poor-quality speakers with good-quality ones.
Check ampliﬁers and the head unit’s ground contact. all grounds should be common.
Check Rca Jack, then replace with a new one or reroute Rca Jack.
Engine noise is caused by poor grounding of ampliﬁers, head unit, other components, battery or alternator, so please check all grounding connections.
