RMS vs peak.
Stereo ratings on watts are kinda like horespower figures.
25 watts peak is almost like saying "at the crank"
Most headunits that claim that kind of power (I don't think the Lancer has an outboard amp, so the power must be coming from the head) are quoting peak figures, just like 90% of the industry. If you went to a stereo shop and looked at a high quality 25x4 amp (as in Rockford Fosgate, Kenwood, SOny, Pioneer, etc.) you would see a device much larger then any headunit. If you think they can pack the electronics necessary to produce the same power as a separate power amp, then you were fooling yourself to begin with. That's why the speakers distort quickly when you turn it up, the head doesn't have enough reserve. It can peak at 25 per channel, but not exceed it. Music has a lot of transients, peaks and valleys. A separate amp may produce 25 per channel RMS, but peak a lot higher, thus less distortion when the bass hits. You wouldn't want a car at which whose top speed is 55-70 mph, even though that's the highest legal speed, you'd want one with reserves to accelerate out of harms way when merging, and not feel all loud and wound out at the top end. Hope this helps.

Wouldn't it be closer to HP or torque at a certain RPM moreso than wheel/crank?
Like you can get 120hp at 5500rpms like you can get 25 watts peak, but the majority of the time you're not making that power? I dunno. Seemed like a better analogy to me.

I think they're decent at low volumes, but I can make them distort without much effort off the stock head unit. all that bass in ya face made you lose ya hearing cliff. They're o.k., but I really can't believe they'd handle 75w without distortion, not gonna do it IMO

They handle excellent at high volume with sufficient clear signal and power(watts) which the JL Audio 300/2 was more than willing to provide to all 4 paper coners.

It is always better to overpower speakers than under power them.
Distortion is caused when a low power amplifier tries to push too hard.
This is the reason the head unit might distort the sound, but an aftermarket amp will make them sound good.
The amp or head unit at least should be the first thing upgraded, then the speakers.
If you were to do speakers first you could really damage them.
