Actually the underpowering is not as bad as the amount of distortion and lets be careful with the 50x4 power rating, that is likely max so the RMS is likely in the 22 watt area, and key to that is at least 1% distortion. Remeber some speakers say they can handle 500 watts rms , but if you send it 499 of distortion the power wont kill it the distortion will and the oppisate sometimes works when I was at JL (jemsen) for product developement review on the W7 they ran 8000 watts into a 13w7 and it didnt blow but this was a reference amplifier running at less than .0008% distortion. A true 50x4 amp is going to be larger than the deck, but as for the speakers if running off the deck spending $800 on MBs would not be really sensicle. i would go with some Alpines or Pioneers, even JL TR series.
