That new receiver will make your factory audio speakers appear much better simply by providing more power. However if you enjoy with the factory radio, avoid directly to the speakers. If you're significant regarding audio, you'll require aftermarket audio speakers. If you have a 4-door (or more) car, start up front where you rest, after that care for the various other locations as your budget allows. Crutchfield carries automobile audio speakers of virtually every shape, type, and dimension.
