[QUOTE="shovelhd, post: 2830624, member: 573327"] You have a fundamental misunderstanding on how amplifier power is made and how current flows. An amp is not force-fed current. Voltage is a potential to make electrical energy. It can't create it on it's own. Current is electrical energy flowing to make work, i.e. power. It can't flow on it's own. Nothing is pushing the current to your amp, rather your amp is demanding more than it should. Power in watts = Volts times Amps In order to put out the same power, an amp will demand more and more current as the voltage drops. If your amp did not have protection circuitry, it would keep demanding currrent until it blew up or blew a fuse. Your "CUR" light is telling you that the current demands are higher than the amp can handle, which generally means one of two things. You either have too low an impedance load on the outputs (subs wired wrong, shorted coils, etc.) or the voltage AT THE AMP is getting too low during the big hits. Get out your DMM and measure it to make sure. [/QUOTE]
