I have no idea how good the stock speakers for the 240 are, mine were blown when I bought got the car but:
If they're really good and worth matching up w/ a decent system then running an amp directly to them (if they're 2 Ohm) will drive the amp twice as hard, make sure you don't run bridged unless the amp is good for 1Ohm loads. Also you'll loose sound quality and gain power @ lower loads unless (like DSC said) you run a pair of drivers in series which brings it to 4Ohm per channel. Other wise take the bridged rms power of the amp and divide by 2 per channel (~double unbridged power)

IOTW: If the amp going in has the specs:
-4 channelsx100watts RMS @4Ohm per channel (net 4 Ohm per 4 channels) THD=X
-2 channelsx400watts RMS @4Ohm per channel (net 2 Ohm per 4 channels) THD=2X
Then:
-4 channelsx200watts RMS @2Ohm per channel (net 2 Ohm per 4 channels) THD=2X

I hope that made sense...
