Installing your amplifier
Planning your system
Before beginning the installation, consider the following:
If you plan to expand your system by adding other components 
sometime in the future, make sure that adequate space is 
provided and that cooling requirements are met.
Consider whether you should use high or low inputs. Your 
amplifier has been designed to accept a low-level (pre-amp 
output from your stereo) signal source. If your source device is 
equipped with pre-amp outputs, you can use them to drive the 
amplifier, so you can connect the amplifier to the two rear 
speakers. Then you can use the built-in power of your source 
device to drive the two front speakers.
Make sure that your components are adequately matched. The 
peak power rating of your speakers must be equal to or greater 
than the amplifier’s. They also must be 1-8 
Ω
 impedance. You 
can find the speaker’s impedance rating by looking on the 
speaker magnet.
Consider the length of your leads (wires) 
and the routing when 
determining the amplifier’s mounting location. Pre-amp input 
jacks require a length of high-quality, shielded, male-to-male 
RCA patch cable.
B- terminal 
(chassis 
ground)
To avoid unwanted ignition noise caused by ground 
loops, the amplifier must be grounded to a clean, 
bare, metal surface of the vehicle’s chassis. The 
ground wire should not be more than three feet 
(one meter) long.
Note
Distortion level is considerably lower from pre-amp (low 
level) outputs.
