It would be awesome if you tell us what HU and what speakers you've got. Are the front coaxes or compos? (I reckon they're coaxes, otherwise you'd mention it). Also, what car does it go in? How much space do you want to sacrifice? All that sort of stuff...
Whatever they are, they're almost certainly underpowered, as ANY HU produces 4x15Watt RMS at most. And yes, forget about 4x50 what you read on the package, that's max peak power, has nothing to do with "real world", sorry.
So, imho you should get yourself a sub and an amp to match. Amp should be a 4 channel. Channels 1+2 will power up your front speakers, channels 3+4 will in bridged mode power up your sub. Most amps will in bridged mode accept only 4 ohm load, so your sub should be a 4 ohm sub. Dont worry if amp produces "too much power (RMS)" for the given sub, thats better then having not enough power fed to it.
As for your rear 6x9's, best thing is to sell them on ebay or alike, and invest the money in the amp and sub. But if you have to have them, they can run off the HU, but set them up not too loud. Remember, you want to hear music in front of you, not behind you!
Another VERY important thing if you want to have a half way good sound is SOUND DEADENING at least your doors and your boot!!!!! This can't be repeated too often, as it's CRUCIAL for a good sound in your car!!!!! Remember also this: All the music you hear when standing next to your car, IS MISSING INSIDE!!!
Wish you luck, if you need more info, or have questions, just ask, I'll help where I can
Wow, good post! That's what i gathered anyway - i'm well aware of that 4x50W being peak power and not RMS.

My HU is an alpine CDA 9813 (i think), producing your favourite 4x50w :P Not entirely sure about what all the speakers are actually, but my rears are some boschmann things that i can't figure out, and i have no idea about the fronts.. or the front tweeters either.

I shall be looking around on gumtree - Thanks.

What sort of sub power should i be looking at? I don't necessarily want to be creating earthquakes, but have a decent amount of it shuold i want to entertain.. And if the amp has too much power won't it blow the sub?
