Sound system Options

[mikecelica]

Currently I have a sony xplod deck, sony 800w amp and single 12" sony sub 1300w, and stock 4 speaker system. The sub is kinda blown, the bass is not clean and distorted when you turn it up. So what Im thinking is replace the current sony sub with another 12" and then replace the 2 door stock speakers and the 2 rear seat stock speakers with aftermarket ones. But what size is a direct replacement for both the front door speakers and the rear seat speakers? And what company should I get the new sub and speakers? I have max of $200 to spend on both the new sub and all 4 new speakers and i dont want any used stuff, learned my lesson once. any help is appreciated. thanks

So are the speakers hard to replace? I was thinking about doing something along these lines, since my driver's seat speaker is blown and rattles/has crappy bass.
