wharfedale has some amplified speakers on their website(wharfedale.com or whrfedaleusa.com)which are pretty cheap i think.I wouldnt go this route however,just because i own some wharfedale speakers and there are better speakers for your money,although i have nothing against wharfedale.matching the amp to the speakers definitely needs to be done but its actually quite simple-check your amps power rating-does it give a power rating into 4ohm and even as low as 2 ohm-if it gives a rating even into 2 ohm than it is very stable and you can use it with any speakers-basically just match the amps power rating to the speakers ohm rating-please note however that speakers ohm rating in use fluctuates so if you use 6ohm speakers with an amp rated into 6-8ohms only(not 4 or 2ohms)you can sometimes run out of power if you play your music loud.also the speakers sensitivity rating comes into play so if your using speakers with a lower db rating (86-87 db)youll need more power from your amp to make the speakers sound louder so you might want to get an amp with slightly more rated power than your speakers require in this case.if your speakers have a high sensitivity (89-90db)you can usually just match the ohm rating of amp and speaker,unless you really crank your music,in which case a little extra power in your amp may prevent the signal from clipping.
