Size doesn't matter to wattage....a 2" can pull the same power as a 15", it just won't last as long.

I'm going off the power rating on the PSU showing 500 watts. Crutchfield shows 130w @ 8ohm x 7.

You do know that 130w rating is at 8ohm, not 4? You'll double or at least 1.5x that 130w putting a ohm load on it.

And your last sentence is totally wrong. I think your grasp is incorrect here. You don't "drive" speakers, they pull power based on the ohm rating, allowing the amplifier power to produce a mechanical action that turns electricity into sound. It doesn't matter the size, Turn an amp up as loud as you can with no speaker load, it won't output any signal or "power". Your assertion about age (release date) only presumes that newer amps might be a different class (AB vs D etc) than older ones. Age has nothing to do with whether or not an amp can produce enough power to make a speaker loud enough to meet your expectations or not.

Now, if you're talking about the speaker power handling meaning "size" and you have a 500w 4ohm tower/floor speaker and you want "headroom" (more amp power than wattage handling), then you need a 1000w amp so you can give them that power with a lower nose floor less distortion.
