POWER CONNECTION
BATT (12V POWER)
Before mounting amplifiers, disconnect the negative cable from the battery to
protect any accidential damage to your amplifiers and audio system.
Connect the power cables to power terminal 12V DC.
All AurA STORM series amplifiers are not equipped with fuses so that external fuses should be used. 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.
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 the ground 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 power antenna
trigger cable. Connect the remote turn on cable to the REM (remote) terminal.

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 cable, then repalce with new one or reroute RCA cable.
- Engine noise is caused by poor grounding of amplifiers, headunit, other components, battery or alternator, so please check all grounding connection.
