COMPETITION FULL RANGE CLASS D AMPLIFIER.
1-Ohm = 1,600Wx1,
2-Ohm = 1,100Wx1,
4-Ohm = 700Wx1

Inputs: 4g power and ground - copper wire required!

It is required with this amplifier, at 2 or 1 ohm, that you MUST install a battery near the amp to help stabilize the voltage with the increased current draw. 
4g size cable on its own cannot support the potential 160a of current draw that is common with this amount of power output. If you have any questions at all please feel free to contact me and I will be happy to help you plan an adequate system to power an amp of this magnitude!
