Not to duspute JeffW's oppinion, but the alpine 9835 has 26W RMS and 60W peak(if you use the 10 guage power wire directly to the battery). This GREATLY exceeds the factory radio specs. Even the RF. however, you will want to rewire around the factory amp. This is going to take some doing... The other thing you need to know is that you should connect the 10 guage power wire to the yellow wire on the radio harness. Make sure you put the inline fuse at least 12" from the connection at the battery. Have fun and do some searches for more information. You have a lot of work to do with that have fun!!!
