Hello guys, again a beginner question: Question theory. How are the effects when I operate a Helix DB 2 with 2 ohms? According to the manufacturer, the power amplifier makes 2 x80W at 4 ohms, 2 x120W at 2 ohms and 1 x200W at 4ohm. If I now hang 2 subs at the amp(parallel.), the impedance is halved (2ohm), the voltage remains the same, so the current should be doubled!?!? What does the amp do? Does the fuse burn? Does the power amplifier turn off? Or how? Or can you not use URI on Use loudspeakers, because they do not have a direct voltage resistance of 4 ohms, but are measured with frequency share (believe 1kHz)? Thanks for the answers, citro-seller
