1998 4runner Factory Radio Specifications??

I have a 1998 Toyota 4runner LMTD ED. with a factory radio/cassette/CD Player, what are the specifications on this?? For example, the RMS that the it puts out the the speakers??

I'm removing the old pspeakers and upgrading but im not adding an amp, so does anyone know what would work best, because I can't seem to find any info on the factory radio.

Does it also have a factory amp???

Thanks

I'm pretty sure it does have a factory amp, my 97' has one. For speakers, you might want to upgrade to an amp because the stock system isn't to powerful. I think its around 180-210 watts, with the amp.
