This depends on what the 6x9's rms rating is. The 300w is the output power. Normally headunits come with around a 50w rms and if this is powering the other front speakers aswell you could well be better off gettin a small amp. Pop down to halfords as most of the ripspeed guys are good at helping. Also make sure that if you have fitted the speakers onto the parcel shelf that the parcel shelf is up to the job, if you get a custom shelf then these are thicker and will work better with the 6x9's.
