Sorry buddy, but you aren't going to drive a set of powerful speakers without the use of a good amplifier (see £100+). And theres no point in buying a good amp and cheapo speakers or visa versa. A reasonable stereo set up would be about £200 ish. NAD 3020 amp, + Mission M70 speakers cost me about £170 I think via Ebay. Bit of twin works fine as speaker cable! Make sure you buy a decent stereo to phono lead though if you're playing from the computer. Mink is certainly correct, always go by RMS power output. Makes me laugh when people quote "Check out the 2000W sub in my car"
