do you have a capacitor? What is the rms wattage on the kole amp And the subs? what is the listening condition when this happens? does the subes start to clip or get distorted?

Are the subs Dual Voice Coil? Are the coils wired in parallel? If yes to both questions, the wires between the terminal and the cone of the speakers do break. When they break they do intermittently work. You need to play each voice coil one at a time to make sure all 4 are working.

Before trying that, play the amp with only the left RCA cable plugged into it. Then play it with only the right one. Let me know what happens.
