help, static only when both rcas plugged into amp!

[papichulo1 0]

I only get static when both sets of rca's are plugged into my 4 channel avionix amp. When i have ony 1 set of rca in the amp it is clear (Static-free). I tested this on both sides of the amp and the same thing happens regardless if i have the rear rca installed or front rca installed or vice versa. ANy ideas?
