[QUOTE="eharri3, post: 5428326, member: 591579"] I ran Eclipse SC8362s which need about 100 watts off of 35, then 75, then 60 and also at one point ran 80 watt front coaxial speakers off the 35 watt amp. Never had a problem. It's all about whether it's gonna give you the loudness level you need to appreciate the clarity and detail of the music without playing funny tricks with the gain or turning the volume up past where your head unit still puts out a clear signal and your amp puts out clean power. A speaker's RMS rating isn't really an absolute indication of what it needs or what it can handle under normal listening conditions, but rather how strong of a flat test tone it can handle continuously without catching fire. It's a general reference point to determine how much abuse it can handle. I wouldn't underpower even the most sensitive speaker by more than half but I would consider overpowering a really good high end one by 100 or 150%. BTW powering rears off the HU is a good idea. If you get everything wired in and don't like how it sounds Id do this and give yourself an easy doubling of power to your front stage without buying another amp. Im now running 140 watts on a bridged 4 channel to my 125 watt Hertz HSKs, which are actually more sensitive than the speakers I used to run underpowered. The deck runs my Infinity Reference rears. I now rarely have to go above 24 or 25 on the Head unit whereas before with some music I had to be close to 29 or 30 to get sufficient loudness.
