i know this topic has been beaten to death, but i can not find a definitive answer with search. i have a infinity kappa perfect 12.1 sub that i want to match with this amp i got from a friend:

i was installing everything when i realized i did not have an LOC, which leads me to my question: the amp says it has high level inputs, which from searching i found means that i do not need an LOC. if i do not need an loc, how do i connect the wires from the sub to the amp? thanks in advance

 

There is a "high" level input connector on the back of the amp.



I assume that the amp come with a connector or pigtail that you can splice into the stock subwoofer speaker lines.
