It's pretty common for the bass driver amp to use much higher wattage than the tweeter/mids. I guess if these amps can drive the whole speaker then they should be able to drive the bass and the upper range will just be a lot of unused power.
It should just draw what it needs to draw I guess. I don't know whether its better to use one amp for L&R woofers and the other for the tweeters or one amp per side driving highs and lows.
