First of all, I'm new to this board and also a proud new owner of a 20GB Rio MK2a. I've been watching the board since I ordered my Rio on xmas last year. I'm happy to see the camaraderie on this board. It's refreshing compared to the mindless slander on most other bulletin boards.

Anyway, my question is about amps. I know nothing about them and only purchased one because the Rio requires it. I'm looking into a Jensen amp since they're cheap and I've heard good things. I still have to decide whether I want a 400 or 600 watt, but I've heard that more powerful amps would damage my factory speakers ('98 Honda Civic). Is this true? I would have thought that some process would regulate the power output so that the speakers wouldn't have any unneccesary strain on them, but I might be wrong. If this is true I'll just go with the lower powered 400 watt amp.

Any suggestions?
