It's either a midrange or it's a woofer. Those are ranges of frequency, not power. If your woofer is spec'd to handle 80 rms watts at 30 Hz, you could. If mounted in a good ported cabinet, your woofer might keep up with the rest of the stock system, though it won't blast out the neighborhood, you might irritate the folks nextdoor. Filters do not change the power of a speaker. Playing more bass may give the impression of power though. What about this; Listen to this speaker on display in the store before choosing it, unless you just feel like experimenting to learn what's what. Just because a speaker is 10" doesn't determine its frequency response or power. The impedance of the speaker will affect how the amp runs it. You're going to have fun for a little while, and learn something. There is no such thing as a *cheap* and *good* system. There's a lot of information you could read- see "the12volt.com". However, diagrams and equations explain much, except actual experience.
