I already have:
-Kenwood KDC-241SA CD Player (4x50watt)
-Kenwood KFC-1361S 13cm Speakers (150watt max)

I am concidering getting two 6x9's for my rear parcel shelf, maybe:
-Kenwood KFC-S6972 4-Way Speaker (450W Peak input power, 80W Rated Input Power)

Will I be able to fit this to my head unit ( if it is a "4 way" speaker, does my head unit need 4 slots for it?)

And do 6x9's make that much of a difference to a cars audio system? and how?
I currently do not have an amp, but may get one in the future, am just wondering if 6x9's are worth it without the amp... I currently only have front speakers
 
Never go by peak power. Kenwood head unit sends about 20-22 RMS to each channel. 6x9 tend to have a lot more bass and hit the lower frequencies better than 5x7 or 6.5 or smaller. 4 way speaker means it has 4 separate speakers. Each plays certain frequencies for example a sub woofer will play around 20-250ish Hz depending on how you adjust the low pass filter. mid range speakers play 80-5000ish Hz. Tweeters are 2000-20,000ish Hz.. The speakers you are looking at play 28Hz - 30000Hz vs. 40Hz ~ 22000Hz on your current. Your ear can hear from 20-20000 Hz 28 is pretty deep for a speaker which may mean you need to amp these speakers because your head unit can't support any more than 22 watt for a period of time if you intend on playing these at any volume. These speakers have 4 ohms (resistance). I haven't heard of a head unit yet that can't support 4 ohm speakers. This is the most common amount of resistance. There will only be one positive and negative on this speaker which connects to your head unit. It is pretty simple. Most of the time the more you spend on speakers the better sound quality you will receive. I personally don't like tweeters and a lot of junk infront of my speaker because it makes me feel like i'm not getting the most out of the speakers when air is blocking it so I go with component speakers where a tweeter is separate from the woofer and there is a box you hook them up to. Go with those 6x9s and you will recieve a lot more bass and your music will sound fuller.
