Appendix C: Building Parallel System Output Cables  

The Parallel Wiring Kits available through AE Techron include pre-built cables to be used for Output 
connections. This section describes how to build your own output cables, if you so choose. 

Select wire appropriate for your application, load and expected output. For 

2105 or 7224

 Parallel systems, 

10 AWG wire will be suitable for most applications. For 

2110 or 7548

 Parallel systems, 8 AWG wire will 

typically be required. 

2120 or 7796

 Parallel systems with a high-impedance load and continuous output at 

less than 60 Arms can typically be wired with 6 AWG wire. However for 7796 systems running high-current, 
continuous-duty applications, #4 welding wire may be necessary. 

If a jump wire is used to connect from the parallel output cables to the load, it should be capable of carrying 
the expected total current output of the system. See 

Appendix A: Wire Current-Carrying Capacity

 for 

assistance in determining the requirements for your system. 

IMPORTANT:

 In a paralleled system, it is important 

to control the lengths of output cables. Output 
cables should be between 2.5 and 4.0 feet in 
length, and the lengths of each leg of the output 
cables should match within ±1/4-inch. See 

Appendix B: Critical Wire Lengths,

 for 

information on critical cable lengths for paralleled 
systems. 

 

Build two cables for output wiring. Each cable 

1.

should contain one leg for each amplifier in 
your system. Color-code the cables using RED 
for the cable to connect to the positive 
terminal of the load; use BLACK for the cable 
to connect to the ground terminal of the load. 

 

The wires should be terminated at one end 

2.

into a spade lug, ring terminal or other 
terminal suitable for the system output and 
adaptable to the connectors on the load.  

 

Terminate each of the legs of the RED cable with ring terminal ends to facilitate connection to each 

3.

ballast resistor. 

 

The legs of the BLACK cable should be un-terminated to facilitate connection into the amplifier’s barrier 

4.

block COM connector.  

See 

Figure C-1

 for sample output cables (used for a two-in-parallel system).
