Intermittantly, when I try to accelerate at low rpm's (like crusing in 4th or 5th) my subwoofers will shut off. They work fine, and as I step on the gas, the "protect" light on the amp comes on and the subs go off, then after I let off the gas they come back on. It isnt a short, that I know of, becuase I can accelerate/decelerate hard, corner hard, go over bumps, etc and NEVER have a problem. Only when I hit the gas, usually in 5th, at low rpms (like 1000-1500), not while just running at that rpm. Any thoughts?
