I'm guessing that your speakers have a peak rating of 250 watts a piece, right? And you'd like to know the rms rating? The best thing would be to contact the manufacturer, but generally speaking, a speaker's rms rating is usually about half it's peak power rating.

Rampage (Audiovox) like a number of other low-end brands lists very misleading "ratings." That "250 watts" means the PAIR together will supposedly handle a total of 250 watts PEAK (or for about 1/2 second) or 125 watts PEAK per speaker. The actual power rating per speaker is probably much closer to 25 watts. Do not expect much from those, or for them to last very long. ------------- Support the12volt.com

Not in this case, unfortunately. Power handling numbers are whatever the maker decides will sell best in that particular market...and the cheapo market uses BIG numbers that mean virtually nothing. If YOU classify them as cheap, and if they actually ARE cheap, then they're CHEAP and won't be capable of producing 125 watts of clean sound. Figure on 40 or 50 maybe and be done with it.
