1.  Disconnect the negative (-) battery terminal. 

NOTE: Check your vehicle's owners manual before disconnecting the battery.  
Disconnecting the battery in some vehicles may require an anti-theft code when 
reconnecting for stereo operation.  Some vehicles may run rough after reconnecting 
the battery and require service to have the on-board computer reset. Check with 
your local dealer if you are uncertain.

2.  Run suitable AWG wire to where the amplifier will be mounted (run 1 foot extra than 

you think you will need). Use rubber grommets where wires will pass through the 

firewall or other areas of the vehicle. Make certain a fuse holder is placed within 18 

inches of the vehicle battery 

 this is mandatory. Do not place a fuse in the fuse 

holder at the battery at this time.

3.  Mount the amplifier on a flat surface. Since a flat surface in a modern vehicle is often 

difficult to find, an alternative is to cut a piece of 1/2 inch wood slightly larger than 

the amplifier mounting area (covered with automotive type carpeting). Mount the 

piece of wood, and then mount the amplifier to the carpeted wooden mount.

4.

Ground the amplifier using the same AWG wire size used for the power cable. Make 

sure the ground location is a clean, unpainted metal surface. 

5.  Run the RCA and Remote turn-on lead to the amplifier from the head unit. 

6.  Run speaker wires (16 AWG or larger) from your speakers to the amplifier. 

7.  Place a suitable size fuse in the fuse holder at the battery. 

8.  Ensure that the crossover is set to "OFF" and that the input level control is set to 

"MIN". 

9.  Turn on the head unit and make appropriate amplifier adjustments.
