the amp doesnt get hot only warm, I am pretty sure I have the amp running at 4 ohm (w/ 2 dvc 4 ohm subs) and it is 2 ohm stable anyway. HOw do I set the level adustment control? The different settings are in Volts, what does that mean? The amp itself puts out 500 rms x 1 and has 3 - 40 Amp fuses but still asks for a 150 fuse. Also i heard the fuse is to protect the wiring not the amp is that true?
