Radio/Amp advice

I have a Galaxy HD29 radio, not sure what it puts out on the low end off the top of my head but on high it puts out 40 watts. I have had numerous compliments on this radio and how it sounds but would like a little more power sometimes. I thought about buying another radio (Galaxy HD47) that puts out 100 watts; it has echo(which I want but it will be turned down, I have heard several people that had their echo turned down low and their radio's really sounded good, wouldn't have known they had echo had I not asked) but don't care for all of the other junk(roger beep, backlit, and etc..). I also thought about switching the radio to low power and use a 100 watt when I wanted. Any suggestions or thoughts?

 

only looking to go up to 150 watts max, don't want to be too much of a jerk.

 

How would this work if I use it with my radio on low power? Also, what is the thing about the crystal that is mentioned at the bottom?

*A crystal must be installed to determine the frequency of operation



Or how about this for an amp?
