Popping sub

[Denarius21]

I have two re audio mt motors reconed by psi. They are powered by two audiopipe 1500s strapped. They are suppose to be 1500 to 2000 wrms. Big 3 upgrade stock alt and battery with small battery in the trunk. At high volumes my left sub makes this popping noise when play at high volumes mostly on lows notes. Like it's in and out. Can someone help
