Protect light on MD Sound MD-2691LT...?

Question

I have two Phoenix Digital PD-130's, thay are 800watt peak each and 320 RMS each at 4 Ohms each. I have them in a bandpass box hooked up to a MD Sound Mono Block Mosfet(MD-2691LT) at 2000Watt peak and 600Watt RMS @4 Ohm, mono power is 1500Watts. Any ideas to why this would be happening? Also, if needed I have an aftermarket head unit installed.

subs could be wired wrong, bad ground, short in the amp, fried sub, or the rcas are bad.

Answer 2

No idea
