Any help with my speaker building questions? Answered

I'm not sure you'll be able to answer this. I was hoping to put one massive woofer (15") and send all low frequencies to it, and then put in two tweeters, hoping that it would somehow overcome the most likely overpowering bass. Is this a viable setup? Ideally, I plan on building these speakers for parties, where I just throw this in the car, drive there, and we're ready to go, don't need to deal with tiny crap speakers anymore. So, ideally, I want to create stereo sound on my tweeters, but just let it go for the woofer, since bass would obviously have no need for stereo. Would I need two crossovers, or just one? In my head, I imagine that I only need one crossover, followed by a stereo amp for the tweeters and a mono amp for the sub. I'm not 100% sure on that circuit though.

I plan on using these parts:

woofer: http://www.parts-express.com/pe/showdetl.cfm?Partnumber=290-340

tweeters: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=296-24635-1-ND

woofer amp: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=296-24635-1-ND

tweeter amp: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=296-18033-5-ND

So, with that in mind, I'd love your help.

Other Miscellaneous Curiosities:
1) If you have any links as to where I can figure out the most audio efficient layout in order to achieve the best sound with this, that'd be a help too.

2) Do I need a mid to help beat the woofer?

3) In order to figure out the required power from the supply, I just need to add the max possible wattage from all the drivers, right?

Thank you, Instructibles community.

That's a really cool design, I like how it allows for both a standing orientation and a 45 degree one as well.

Also, concerning construction. I was going to build these out of reasonably thick MDF, and I'm working on the sizing for the enclosure. The woofer wants at least 11 cubic feet, so I'm working off that. I'm considering 4'x2'x1.5'.

Just a quick comment while I think about the rest of your plan. You do realize that the amps you've picked are just the integrated circuits and you will have to add lots of parts and hardware to have a working amp. don't you?

Nope, had no idea. Thank you, I'll read more. I feel silly now. -_-
