There are several factors to consider before installing Earthquake 
Sound’s iQuake-52.

•  What are the intended listening zones?  

•  What system options and accessories might be required for features 

such as local sources, etc.?

•  From where in each zone will the listener prefer to control the system?  

Where will the remote gains be located?  Where will the speakers be 
located?  

• Where will the source equipment be located?   

•  Keep all power cords away from all signal cables to prevent humming 

from induced noise.   

•  Choose reliable signal cable cords (Earthquake Sound also specializes 

in high performance RCA cables and patches).

•  All speaker wires that are ran through the walls should be twisted type 

to reduce potential hum noise pick-up.

•  Label both ends of all wires with the corresponding room location.

•  It is best to use a grounded electrical outlet to power the amplifier.  

Lack of input ground reference could be unsafe.  Consult with your 
electrical contractor about proper grounding.
