hmm why did you put the tweeters behind you?
i would put them in the front door panel somewhere it should give you better imaging. as for the distortion, do you have the tweeters hooked up to the crossovers correctly there should at least be a capacitor in line with the positive lead if your components and sub are connected to the same amp check your crossover settings on the amp. if its a 4 channel w xover for front and rear set your front channels on the components high pass no lower than 100Hz. if your running tri mode w/ a 2 channel amp youll need passive xovers for all your speakers and set you amp for full range. what kind of amp are you using? 2/4 channel?
