Dunno about the amp specs dude, but what i Can tell you is....it is a GOOD thing to over power your speakers rather than under powering them, believe it or not....but lesser power can blow the speakers much faster than having more go through them.
some of the guys talking over at www.streetsourcemag.com
were talking about this, and they all agreed on putting about twice the amount of power a speaker can handle.
which means if your speakers are rated at 90Rms then you would want power from your amps to each somewhere in the range of 180Watts. not much more than double though, you dont wanna get too crazy with it.
Anybody else agree with me?
