if you get the audio system upgrade then it is amplified. this is when you will run into your exact problem. there are a few component 5x7 speakers out there, but i prefer the JL audio because of the volume they can play. the c3 or the c5 components are the ones to use. i can get you a good deal on some speakers if you go this route. if you do not want to spend that much, then i think infinity or kicker make a cheaper set. whatever you choose they should have no problem being amplified when you do add an amp. make sure to purchase your speakers through an authorized dealer because you will not get any warranty of any kind if you do not.
