POWER CONNECTION
BATT (1 2V 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 AurA VENOM ULTRA 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 (C3ROUN D)
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”½” (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.
RCA INPUT CONNECTION
IMPORTANT! AurA VENOM ULTRA amplifiers support direct speakers output connection to the RCA inputs of the amplifier without the use of additional Hi/Low converters. To connect, use the adapter connectors included in the kit. Input sensitivity (GAIN) should be set to the left position (10V).
SPEAKER CONNECTION
- AurA VENOM series amplifiers have protection features to prevent any damages from misuse or faulty conditions.
- If VENOM 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 AurA VENOM series amplifiers shuts 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’ rounding, short & voltage.
- Please check the fuses. If they are blown, please replace with 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 head unit’s ground contact. All grounds should be common.
- Check RCA cable, then replace with new one or reroute RCA cable.
- Engine noise is caused by poor grounding of amplifiers, head unit, other components, battery or alternator, so please check all grounding connection.
POOR BASS RESPONSE
- Please check speaker cables and revers polarity.
