Is my amp powerful enough?

[QUOTE="RSDXzec, post: 7614353, member: 638347"] I was referring to max on the head unit, before I set it up I found conflicting information on the internet of whether to set the HU at 75% or 100% when setting the gain, so I had my head unit at 100% when I set it because I figured that way I wouldn't be able to set the volume any higher. I used this as a guide [URL="http://www.youtube.com/watch?v=suX13VixU5k"]http://www.youtube.com/watch?v=suX13VixU5k[/URL] But after your statement I think I'm going to reset all my gains at 75% Sorry, I shouldve used units in the equation it was (185WRMS x 4ohms)^1/2 = 27.2Volts... btw ^1/2 is the same as sqrt 185WRMS coming from the amp at 4 ohms due to the speakers being 8 ohms each wired in parallel. And I believe this amp is only stable at 4 ohms. If less resistance puts more strain on the amp then is it safe to assume this amp could handle a single 150WRMS 8ohm box by itself? I never heard of the box rise Vdrop, but I believe using thin wires was my mistake in this setup, but I will definitely be checking the voltage afterwards and any difference then I will count as box rise Vdrop.
