RMS capabilities

to answer IllusionsX's question..... his buddy was running a Class A/B amp which is about 50% efficient... so... his 400 watt speaker amp really was pulling more like 800watts. The 200watt amp may have been Class A/B (50% efficiency) or maybe even a Class D (70-80% efficient).

Now days most people run subs off Class D amps because it saves a lot of power, and means you can get more rms before your electrical system becomes the bottleneck.

Upgrade the Big 3, and that'll help most people squeeze out a few hundred more watts

you are right about the AB class amps... but.. why would anyone sacrifice sound quality for more power? :) I would not go for a class D at any time soon lol
