FULL RANGE MONO
This application illustrates the basic mono bridging method for all Autotek 2 channel amplifiers.
Interconnect cable checklist:
A MONO signal source is required, such as would be available from the mono sub bass output of an active crossover, whether stand alone, or built into a head unit or equalizer. Important: Do not be tempted to connect the hot, or positive outputs, from any source together to obtain a mono signal, as this could very well damage the output stage of that source.
It is necessary to feed the SAME signal to both left and right inputs via a Y- adapter RCA cable. Connect the mono speaker positive terminal to the RIGHT +, and its negative terminal to LEFT 
Switch setting checklist:
- The AMPLIFIER 
Crossover frequency control setting checklist:
N/A for full range operation.
TIP: If you are using the mono sub bass output of an active crossover, there is nothing wrong with switching in the low pass filter in these amplifiers for a steeper low pass

The HIGH LEVEL inputs are used when the radio/CD player does not have RCA cable outputs. You can connect the radio/CD player speaker wires directly
| to the amplifier via the high Level Inputs. | Use this connector for 2 CH amplifiers | Use both connectors for 4 CH amplifiers |
