Is my amp powerful enough?

[QUOTE="mast240, post: 7614321, member: 631695"] 1. when you say "max volume" are you taking it to the very highest volume on your HU, or 3/4 of the way? most HU's will start to clip the output signal at around 3/4 volume, so that should be your max volume. 2. from the equation you posted, it seems as if you're running your amo at .5 ohm? if so, this could be the reason your amp is running much warmer... the lower impedance you run, the more strain you create on your electrical and amp.... so, you might want to check with a DMM and see what you are actually wired to, and wire to 2ohms if needed. 3. the voltage drop you are seeing is most likely due to box rise... any sub that is in a box, no matter how efficient the box, will have box rise... meaning that as the sub plays, the actual load impedance (ohm load) will rise, which in turn will mean the amp puts out less power... which in turns make your output voltage drop. also, please read this sticky, as it answers alot of frequently asked questions....
