what kind of sub are you running? we need a little more info to help you out.

 

sorry i have a pioneer 12 800 watt max.

 

sounds like your getting clipping by having the gain set too high. or, one of your connections is incorrect, like the the positive speaker wire is touching the negative speaker wire some place.

 

im gonna have to say the same thing.. try turning the gains down.. use volume before you start upping the gain. lightning audio amplifiers are pretty much a joke, so id also invest in a better amplifer.. and a better sub at that.
