whats you want to do is look at the RMS wattage value (continuous/nominal power) of yer amps and match em to yer speakers/sub(s). don't worry bout peak.

it doesnt have to be exactly.. the rms values of speakers and and subwoofers is a thermal rating of how much wattage the voice coils can take.. it would be ideal to get a more powerful amp ( exceeds the RMS ratings) so that u can turn the gains on the amp down a bit .. still fully power the speakers but ur not working the amp as hard.. peak power numbers dont mean anything .. dont even pay attention to those.. alot of companies will mislead u with low RMS ratings and then have a jacked up peak power rating that they advertise.
does subwoofer draw power? or only receive them from the headunit and from the amplifier???
I know a speaker is only for output, but I 've always wonder if for example i have a 100 RMS watts RMS subwoofer, and a 200 rms watts amplifier, what current is it really drawing? 200w (from my amplifier)? or 300w (100 + 200 sub + amp)?
