I don't know the exact wattage, around 20-25? If I were you I'd buy a good 4 channel amp with around 50-75 watts per channel. You may need an RCA converter if you don't have an aftermarket deck.

Does anyone have the specs. on the stock premium sound amplifier? How many watts per chan. and ohm factor? I have replaced my speakers with Infinity Reference Series and am utilizing the stock premium amp. It sounds much better than the old speakers, but I don't think they're seeing enough juice.

Thanks, Roy

How did you hook up the premium amp to new speakers, do you have a new head unit? Any info about the amps would be gretly appreciated.
Thanks
