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.

THANK YOU

Thank you for choosing Earthquake Sound’s line of TNT amplifier: the best way to
factory mobile audio system. With proper installation and responsible listening, your amplifier(s)
will give you years of near perfect sound reproduction.

We strongly recommend you to have your new amplifier(s) installed by an authorized Earthquake
Sound dealer. Installation professionals employed by your dealer have the correct tools and
knowledge to install your amplifier(s) neatly and successfully. Also, when your new products are
installed by an authorized dealer, your product will include a FIVE (5) YEAR LIMITED
WARRANTY. If you choose to perform your own installation, your warranty will be subject to
limitations. Dealer policies on handling warranty requests may vary from one dealer to the next.

Please read the warranty information in its entirety and use good judgment when making these
vital decisions.

CAUTION:

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.
