Speaker RMS vs. Radio Power

[mrlewp]

Just wanting to replace basic speakers in car. They are 6X9 in. The new radio is only rated at 17W, and that's adding! the 4 spkrs., which I know isn't a true value.
Regardless, dilemma is finding a simple pair of spkrs. that's not rated at a billion Peak watts! (ha) I really find it not believable that a pair for $30 can be capable of handling
350 watts, but will a very low power device sufficiently drive a spkr that's in a much higher league?
Only online have I seen some rated at 30W for ex., which would seem a far better match to me. Please, only if you know for sure- not just a hunch or feeling. Anyone know, can I pick up the ones in store (350W), or seek online for ~20W, 30W, or so?

The power ratings in car stereo are insanely screwed up. The guy buying the 1000w amp for $79 will get a pair of cheap speakers that claim to work with 1000w amps. Reality is both are bull. An inexpensive speaker is probably going to be fine with your 17w. The only issue is the impedance. Some car speakers are 1 ohm so make sure that the head unit is compatible with the impedance of the speaker you get.
