it'll be fine; however, it might sound a little different than your last setup. it might sound better or worse depending on the head unit you have. a sony head unit claims to have 55 watts of power, but it sounds hollow. a pioneer deck claims 45 or 50 watts and it sounds like you have an amp hooked up.

i suggest that you go to a store with multiple stereo display boards and listen to all of them first.

good luck :thumbup:
