I have a Brutus 1500D amp and am running it a 1 ohm. The amp is rated at 1500 watts rms at 1 ohm. Now i just spend a bunch of money on the system and want to set it right. I looked on the internet and couldn't find the formula for voltage output of the amp. Im trying to set it so that at full volume(before the HU starts clipping) the amp wont clip. How many volts should i be looking for at max volume??? i know there is some forumla that involves square roots and stuff, if anyone can tell me what voltage i should set it to it would be greatly appreciated
