Any idea how many watts the built in amp on the stock (am/fm cassette) headunit has? My goal is to be able to plug in my ipod. I will probably have to buy an aftermarket headunits, but I am not looking for a killer system. Just something with similar output to stock.

The stock head unit has between 150-200 watts. Some devilles are diff than others mine has a stock amplifier but has the equalizer on the head unit. (im swapping the whole audio system out and installing SONY Explod 4 way speakers all the way around, 2 12 inch sony explod subs, and a Boss audio amp and boss audio head unit.
