How many watts a 1998 oldsmobile achieva stock stereo puts out?

I have a 1998 oldsmobile achieva. I have a stock stereo and speakers. I am looking to replace the speakers but cannot find information on the stereo anywhere. it only has a cassette player, no cd player. If someone could tell me how many Watts it puts out? Please and thank you!|||Usually there is a wattage marked on the magnet frame of each speaker. You'll have to look at them. The stereo is less than or equal to that. It wouldn't hurt a bit to use replacements that are rated for higher wattage. That won't make them play louder, but it will help the speakers last longer. Also pay attention to the impedance which will be something like 4 ohms or 8 ohms. Don't use lower impedance than the stock speakers.|||if it has the an amp in the trunk probably 200 peak and 100 rms, otherwise a stock radio like that is around 40 wattsx4 peak
