Earthquake Amplifiers are capable of generating high sound pressure levels. You should
exercise caution when operating these amplifier systems. Long term exposures to high
levels of sound pressure will cause permanent damage to your hearing. Sound pressure levels
exceeding 85dB can be dangerous with constant exposure. Set your audio system to a comfortable
loudness level. Earthquake Sound Corporation does not assume liability for damages resulting from the
direct use of Earthquake amplifiers or other Earthquake products and urges users to play their music at
moderate listening levels.

CAUTION:
SIGNAL SENSING FEATURE - AUTO ON/REMOTE ON
This TNT amplifier features the new, improved and more powerful circuitry. Better yet,
Earthquake Sound has added a special AUTO SIGNAL SENSING Feature which allows
installers to turn on the amplifier without using the remote wire.
By simply connecting the RCA or Speaker level inputs to the amplifier, it will turn on
automatically when it senses an audio signal. This feature makes upgrading the sound
system in many of the latest model vehicles easier for installers as it eliminates the need to
connect a remote turn on wire to the amplifier.
Before you proceed, please note the following:
!
This feature may not be compatible with all latest model vehicles.
!
If your vehicle is going to be parked for over 4 weeks, then you should disconnect the
main fuse of the amplifier.
!
Be sure to follow the connection instructions and illustrations below.
AUTO ON
When the switch is on AUTO ON, the amplifier will
automatically detect an incoming signal when the stereo is
turned on. If the amplifier does not detect any signal after 20
minutes, the amplifier will automatically turn off.
The proper power and remote wire connection when using the AUTO SIGNAL SENSING is
illustrated below.
DO NOT connect the remote wire to the head unit as this will damage your sound system.
RESET
In case the system goes into protection, simply turn off the
audio source, lower the volume and slide the switch to RESET
then back to AUTO ON position.
REMOTE ON
When the switch is on REMOTE ON, the amplifier relies on the
remote wire to detect the signal and turn the amplifier on or off.
NOTE: RCA outputs must be inserted in CH1/2 for the amplifier to detect any incoming
signal.
