Hi Navin,
Yes, I calculated with more or less same percentages. For me, under 2000 hz where my cross-over is, should be around 75% of the music / energy. So, for a single channel driving both woofer and tweeter, the mid bass driver would get only 12 watt out of 16 watts of toal available power ( Lets assume). But now it is getting full 16 watts to drive only the woofer i.e 33% of power of hike effectively which is not negligible, what do you say?

I agree that it sill cannot beat the solution of having an external amp, but again I have limitations as explained earlier.

Anybody heard Blaupunkt Acapulco MP54 ? I'm getting this one really cheap, around 40 USD. How is the SQ?

Blaupunkt HUs generally have a very neutral sound, and are VFM. At USD40 it would be a really good deal, especially since it has 3x 4v Pre-outs. Make sure to get the separate accessories like Aux-in and iPod interface cables when you order this.
