Precautions: Read First!

 

 

If after reading the direction you feel uncomfortable about installing the amplifier in your car, or not 

equipped  or  competent to  do  so,  you  should  have the  amplifier installed  by  an  authorized installer. 
It's your car! 

 

Negative battery terminal must be disconnected before any electrical connections are made. 

 

Be sure choosing a location that provides substantial ventilation for the amplifier. 

 

The most preferred locations would be in your car's trunk, under the front seats or on the back wall of 

a truck. 

 

The  location  chosen  should  provide  at  least  2"  of  clearance  above  the  amplifier  for  adequate 
ventilation. 

 

If the amplifier is to be mounted vertically be sure that it is in a place where adequate air will flow 

along the length of its heat sink fins for cooling. 

 

NEVER  mount  the  amplifier  up  side  down;  this  will  cause  the  heat  to  rise  back  into  the  amplifier 
causing thermal shutdown or possible permanent damage. 

 

NEVER mount the amplifier in a location that is subject to direct sunlight or exposed to moisture. 

 

Be sure to mount the amplifier to a strong, solid surface, which will not give way under the stress of a 
sudden stop or accident. 

 

Make sure that the mounting screws will not penetrate the gas tank, brake and fuel lines, wiring or 
other critical parts of your car when installed. 

 

NEVER operate the amplifier without the proper power and ground wire 10 gauge minimum. 

 

NEVER operate the amplifier without proper fusing. Fuse holder must be located with in 0.5 meters 
from the battery. This fuse is to protect the car not the electronics. In case of a short, the fuse will 
blow instead of the wire burning up. Using other than the recommended fuse ratings at the battery 
and at the amplifier may cause damage to the amplifier and will void your warranty.
