POWER CONNECTION

Dragster High Performance Amplifier

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.

POOR BASS RESPONSE

  • Please check speaker cables and reverse polarity.
