I bought my stuff from Millionbuy.com. Got it really fast, the prices were really good, and they provided me with tracking info for free. I would figure out what you want to put in, then do a search for the model number through google or dogpile. Then go from there. Check the dB rating too. The higher the louder, but be careful or sensitivity range... the 6x8's can only handle so much bass.
