bridge the amp, 100W should be pretty good, but i would put a little more power if you have some.

bridge the amp and put all the power on the fronts.

they would still like quite a bit more but it'll work.

the rsd's love power.

Agreed. I run my RSD65CS to my M25 and run the Boston Acoustic 6" coxial off deck power. I actually cut the tweeter wire off the coaxials and mostly fade to the front. I really only use the rear when I have passengers or I remove the sub for maxium trunk space.
