I have a 2005 Honda civic and want to upgrade the audio system a bit. I don't need or want something that can be heard from blocks away, just something cleaner sounding than the factory system. Will a HU be the best place to start or speakers? Can I add component front speakers eventhough I have only 2 door mounted? How? What companies do you recommend that I look at for HU and speakers....I would like to keep it under $800 Canadian for the whole setup. Any input or suggestions are much appreciated and thank you in advance!!
