It is important that you read this manual very carefully and follow it for your installation carefully.
Before you start your installation,please consider following concerns.
1. Disconnect the negative (-) battery cable before mounting the ampl r orma king any connections.
Check the battery and alternator ground (-) connections. Make sure they are properly connected and
free of corrosion.
2. Before selecting a mounting location for ampl r, please take some concerns into consideration
with cooling e ency and safety.
3. Power connection
Before installing ampl r,disconnect the negative (-) wire from battery to protect any accidental
damage to your ampli and System.This Ampl r is designed to use 4 AWG POWER and GROUND
cables.
4. Ground connection
Locate a secure grounding connection as close to the ampli r as possible. Make sure the location is
clean and provides a direct electrical connection to the frame of the vehicle.Connect one end of a
short piece of the same size cables as the power cable to the grounding point.Run the other end
of the cable to the ampli loc ation. Connecting the ground cable to the screw terminal
labeled as GND.
5. Remote connection
Run a remote turn on cable from the switched +12V source you will be using to turn on the system
components. This may be a toggle switch, a relay, or your source unit`s remote trigger wire, or power
antenna trigger wire. Connect the remote turn on cable to the power terminal labeled as REM. Run
this lead to the ampli 16AWG wire or larger.
