Nextar N CU 160 User Manual

Make sure that you have a good chassis ground.  Good ground connections will eliminate 
most electrical noise problems.  A good chassis ground requires a tight connection to the 
vehicle's metal chassis.  The area around the ground connection should be clean, bare 
metal without rust, paint, plastic, dust, or dirt for a good electrical connection.

This unit is designed for use with four (4) speakers with an impedance between 4 ohms 
to 8 ohms. 
An impedance load of less than 4 Ohms could damage the unit.
Never bridge or combine the speaker wire outputs.  When not using four speakers, use 
electrical tape to tape the ends of the unused speaker outputs to prevent a short circuit.
Never ground the negative speaker terminals to chassis ground.
