GND ( GROUND )
Locate a secure grounding connection as close to 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 gauge 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 sw 12V source . This may be a toggle switch, a relay,
your source unit's remote trigger cables, or power antenna trigger cable. Connect the remote turn on cable
to the REM ( remote ) terminal.
12V ( POWER CONNECTION )
Before mounting amplifiers, disconnect the negative ( ) cable from the battery to protect any accidential damage
to your awesome amplifiers and audio system.
All amplifiers are designed to use 4 gauge power and ground connection.
Connect the power cables to power te 12V.
SK-M5001D and SK-M4004D do not have built-in fuses so they need external fuse connection.
Connect one end of fuse holder to the power cable going into the amplifiers and the other end of fuse holder
to 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 holder adequate for the application.
SPEAKER OUTPUT
This terminal connects the amplifiers to the speaker systems. Minimum speaker cable should be larger than
12 gauge.
Connect carefully the subwoofer speakers by checking the impedance 1ohm for SK-M5001D and 2ohm stereo or
4ohm mono for SK-M4004D.
4 ~ 1 ohms
SK-M5001D speaker connection
4-4. SK-M5001D speaker connection
SK-M5001D Minimum working impedance is 1ohm.
Impedance lower than 1 ohm can damage the amplifier
Caution !!
