Like any aftermarket system, they would sound "better" with an amp, but they will run off the stock system as well as an aftermarket deck. Just dropping these in place of the stock speakers will be a WORLD of difference. If you want to step up to an amp later they will have an increase in loudness capability and the sound will be sharper.
