Question about this here Rockford Fosgate amp...?

Question

Alright. A freind of mine has a Rockford Fosgate Punch 200a4 amplifier. It seems to be kinda old. Its heavy as my amp (And mine is probably 2 times bigger then this one) and its..well..dusty and c**p. It's a 4 channel amplfier. Bridgible..blah blah blah. He let me barrow it to see if I could clean it up for him. But, there are these RCA inputs in the middle of the Right and Left rear inputs, and the Right and Leaft front inputs. The inputs between the two are labeled as Pass-Thru. What does this mean...? What does this input do?

Answer 1

These give you an rca output. The output will be an exact copy of what is coming in the rca inputs. This lets you pass the original signal to another amp so you can have more than 1 amp.
