Answers: If you are looking to replace the factory speakers you want to look for speakers with the extreme possible efficiently or sensitivity. That number determines how effectual a speaker is at using the power that is given to it. Power handling really isn't much if a concern here if your not planning on using an amplifier. So if you be looking at speaker "A" which can handle 500 watts beside an efficiency of 90 dB and set B specifically rated at 150 watts next to a 94 dB efficiency the set B would be the better choice since they use the power more effectively and would run out up being louder.
Any speaker will work next to a 50 watt amp. 425 watt speakers are its theoretical power factor, but is mostly fluff.
If you want bass, shell out another $100 or so and install a bazooka tube subwoofer. Google it.
